Externally trigger hr2000+ spectrometer with dg535 delay generator

Hello all,
I have three Ocean Optics HR2000+ spectrometers, an Ultra 100 laser, and a Stanford Research Systems DG535 delay generator. I'm using the delay generator to trigger the laser, shortly followed by the 3 spectrometers (all 3 simultaneously).
I've managed to get this procedure working in SpectraSuite and tried to replicate it in LabView using the HR2000+ LabView drivers. The spectrometers have individually worked in normal and external trigger mode in LabView, but as soon as I try to fire and sync all 3 spectrometers using the delay generator, LabView staggers their waveform acquisitions to happen one at a time. This defeats the purpose of the delay generator.
I tried using a flat sequence structure to make sure the integration times and triggering modes have executed before the waveform acquisitions begin with no success.
The attachment shows my code before I had a flat sequence frame between the trigger and waveform acquisition functions.
The delay generator has been controlled both manually and through LabView as well. I'm using a Win 7 machine.
Thank you for any help!
Sincerely,
Mike

Hi Daniel,
Attached is the driver I used.
My code looks more like the Acquire Multiple Waveform VI under the Example folder.
Are you suggesting I do something similar to the Acquire Continuous Waveform VI?
Everything works up until the simultaneous part, and it also works one spectrometer at a time.
Thanks!

DAQCard 1200: How can I send two TTL singals on separate channels with adjustable delay shortly after (typically a few milliseconds) external triggering?

Hi, this is probably a simple question, but I have never used the digital and timing part of any DAQboard before... I wish to use an old Power Macintosh 7200 with a DAQCard 1200 for timing and synchronizing external events . The scenario is as follows; an external device (in my case; a CCD camera) sends a trigger signal (TTL, 600 ns). I want this signal to trigger the DAQCard, whereafter I want the DAQCard to send two TTL pulses (20 microsecond duration) from two separate channels (one pulse from each channel). The first pulse must be sent within a few milliseconds after the trigger is recieved. Th
en I wish to be able to control the delay from the first pulse is sent and to the second pulse. This delay should preferably be adjustable from a few microseconds and up to at least 20 milliseconds. How can I achieve that kind of operation? (I need a few tips to get started.. like for instance: should I connect the external trigger signal to the EXTTRIG pin or to the gate pin of one of the counters? Do I have to interconnect the counters in some way? Do I have to invert the OUT signals? etc..)Thanks for your help in advance.
regards,
Michal

I have not personally used the DAQCard 1200, but if it is similar to the E-series devices, you route the trigger signal to the gates of both counters.
In your code, use the Data Acquisition->Counter->Generate Delayed Pulse VI twice, once for each counter. You can then set an input on that VI to select to trigger on the gate, and set the delay and pulse width of the pulse. Since both will start from the same trigger, you can delay either pulse as long as you wish, from microsecond to seconds, making the second pulse follow the first.

Ask to connct the External Trigger (TRIG) to the Function Generator (FGEN)

Ask to connct the External Trigger (TRIG) to the Function Generator (FGEN).
like to control of the start the function using the External Trigger, how i can do it ?

tamar2010,
The VirtualBench Function Generator does not support generation triggering. You can export a trigger with the Function Generator, but you you cannot import a trigger and start generation from it. Please refer to page 6 of the spec doc for more information:

How to externally trigger the execution of TestStand with a start and abort button through a digital interface?

Hello,
I'm Currently evaluating TestStand as an alternative for an in-house developed Test Sequencer.
To start our own Test Sequencer we use a small box, connected to a DIO board. The box has a start button and an abort button. The box also has a pass, a fail and a running led.
The interface with this box is made via some digital lines of a PCI-DIO-96.
In our own Test Sequencer we have groups named Init, Run, Abort, Exit.
The Init group is executed at startup (only once). It is used to initialize all the HW and SW. -> I guess this is the Pre UUT Loop callback in TestStand.
The Exit group is only executed once at the end of the day when the application is terminated. It is used to free all the used hardware and cleanup all the resources. This probably is the Post UUT Loop Callback in TS.
When a product needs to be tested, the operator presses the "start" button which triggers our own Test Sequencer and the run and abort group are being executed (first the run group, afterwards the abort group).
When the product is being tested the "running led" of the little box lights up to indicate to the operator that the application is running. (only when the run and abort group are running)
The Run group has all the functional tests in it. (MainSequence)
The abort group is used to put everything back in it's original state after the test on this single product is done. (Post UUT)
When executing the tests and something goes wrong (operator gets stuck in a clamper, ...) the operator can still press the abort button and then the execution immediately jumps from the currently executing step in the run group to the first step of the abort group. So, when something goes wrong, immediately the abort group is called.
At the end of the run and abort group, if no errors occured, the "pass led" lights up. If one or more steps went wrong the "fail" led lights up.
This setup can also be used to test multiple product in parallel. At that time all the different parallel testers have such a small box which contains a "start" and "abort" button and a pass, fail and running led. (it is possible that they are all connected to the same PCI-DIO-96 board. )
My question:
Is it possible to do something similar like this in Teststand? If yes, is there an example available that shows me how to do this in TestStand? (externally trigger the execution of TestStand)
Typically, in the Init group (Pre UUT Loop) the digital interface box gets initialised.
In the Close group (Post UUT Loop) the digital interface box is taken out of scope.
Note: The PCI-DIO-96 board to which the digital interface box is connected will also be used in the rest of the developed application (MainSequence, ...)
What's really important for me is that I can create a process model that all the application developers in our organisation can use. I really don't want any of the application developers (limited software experience) to mess around in all the features of TestStand.
For them it's important that they just add the function DigitalInterfaceBoxInit () in the Pre UUT Loop Callback and the DigitalInterfaceBoxClose () in the Post UUT Loop Callback, and then everything works!
It is important that the appliation developers do not have to create any global variables, other functions, synchronisations, parallel sequences, ... in TestStand. All this needs to be done with a simple call to the DigitalInterfaceBoxInit function.
Thanks in advance for all the help!

Dennis-
Your application sounds very well suited to TestStand's abilities. I am also quite impressed with your knowledge of how TestStand's architecture is arranged when you are still just considering whether or not to use it.
I think that TestStand would work really well for you in this application. Like you mentioned it will provide you with a form of standardization for your application developers to work from. It also provides the flexibility for you to add your custom routines in many different places. TestStand also makes parallel and batch testing much easier in TS 2.0 so that you could develop one test for your product and execute different instances of it in parallel to test multiple products at once.
As for your specific question about how to c
ontrol TestStand using a DIO board. I think this is very feasible and should not be too difficult. Since TestStand provides you the ability to create a custom operator interface your operator interface could monitor the status of your DIO board and launch/abort executions based on the read values. Usually the executions are launched/aborted when a button on the GUI is pressed however, I do not see any thing different about basing the action on a DI signal vs a mouse click. I am sure your application is more involved than this high level description but from the sounds of it I think it is very possible to do with TestStand.
Based on my experience of building test systems with TestStand and your description of the application, I would feel very confident in using TestStand to achieve all the goals you mentioned. If you have further detailed questions on how one of your features might be implemented, feel free to contact one of our Application Engineers or email us at www.ni.com/ask
and we would be glad to help you.

Data-acquisition with NI 6036E DAQ card & GPIB using an external trigger

Hi all,
I hope somebody could give me some help with the following and answer some questions:
Simple system description:
Labview 6.1
PCI-GPIB card
6036E DAQ card
In my system, I am using an external analog trigger signal (A) for continuous data-acquisition. Characteristics of the analog trigger signal (A) are: ~40 Hz, signal height +1.48V, triggered by rising edge (the analog trigger signal (A) could be changed to a TTL signal). Each data-acquisition is done within ~1.0 ms after the rising edge of the trigger pulse. The timing of the data-acquisition and analyzing procedure is controlled by execution in a sequence structure placed in a loop.
Now, I connected a power meter to the system, to measure the laser power during the data-acquisition. The power meter has two options to provide the laser power data:
a) via analog signal output (voltage corresponds to laser power in watts)
b) via GPIB (direct output reading of laser power in watts).
Problem:
During a certain point in my data-acquisition sequence structure (defined by a frame), I want to use the next occuring analog trigger signal (A) to acquire 1 value from the power meter.
How do I do this in Labview programming for the following two situations?
a) If I connect the analog output from the power meter to an analog input channel of the 6036E DAQ card. The analog trigger (A) would be connected to a second analog input channel (In case the analog trigger signal (A) is changed to a TTL signal it would be connected to the PFI0/Trig input pin on the DAQ card).
b) If I use the GPIB connection of the power meter. The analog trigger (A) would be connected to a second analog input channel (In case the analog trigger signal (A) is changed to a TTL signal it would be connected to the PFI0/Trig input pin on the DAQ card).
An other possibility would be to trigger the power meter directly, so it outputs constantly power meter values at ~40 Hz. How could I than acquire 1 power meter value (at a certain time im my sequence structure) via analog input at DAQ card or GPIB?
Additional questions:
How do I configure the PFI0/Trig pin on the 6036E DAQ board individually as an INPUT?
How do I use an analog trigger signal (A) as counting signal for a loop, or as an activation signal for a sequence structure which includes GPIB commands?
It would be very nice if somebody could give me some help.
Kind regards,
beam

Hi beam,
I just want to verify that I understand your situation correctly:
An external trigger signal (A) is wired to one of your input channels (e.g. CH0) to trigger data acquisition of a second channel (e.g. CH1). Your power meter is connected to an analog input channel, which you would like to trigger with a certain rising edge at some of your sequence structure.
Problem:
During a certain point in my data-acquisition sequence structure (defined by a frame), I want to use the next occuring analog trigger signal (A) to acquire 1 value from the power meter.
How do I do this in Labview programming for the following two situations?
a) If I connect the analog output from the power meter to an analog input channel of the 6036E DAQ card. The analog trigger (A) would be connected to a second analog input channel (In case the analog trigger signal (A) is changed to a TTL signal it would be connected to the PFI0/Trig input pin on the DAQ card).
If a task has been configured to acquire signal from one analog channel, it's not possible to run a second analog input task or to add a second channel on the fly. You had mentioned that it's possible to read from the instrument through GPIB. Is it possible to perform a software trigger such that at a certain frame of your structure, when the trigger signal A reaches voltage "x", a GPIB command is written to your power meter to query a measurement reading?
Additional questions:
How do I configure the PFI0/Trig pin on the 6036E DAQ board individually as an INPUT?
You do not need to explicitly configure the PFI0 line as an input. If you want to use it as an input such that it acts as an analog trigger, simply wire the trigger signal to this pin. When configuring the trigger in your software, specify PFI0 as the trigger source.
How do I use an analog trigger signal (A) as counting signal for a loop, or as an activation signal for a sequence structure which includes GPIB commands?
You can try using the Limit VI to find out when the trigger signal reaches a certain level, and count how many times this level is reached. Similarly, you can use this as the condition to execute GPIB commands.
Hope this helps,
Lesley

[Question] PCI-6220: digital level at the pause of a continuous impuls train with external trigger

Hallo,
I'm trying to use a PCI-6220 card to generate a continuous impuls train which will be paused at an external trigger. I've used the example code in the example library to generate the impuls train. The idle state of the impuls train is set to be high. But I figure that die digital level at the pause is sometimes high and sometimes low. I suppose that the level stays at the exact time when the pause begins?
Is my assumption correct? Is there any way to let the impuls always pause at the idle state, like it will then be paused after a full impuls is finished? Any tips or links will help. Thanks in advance.
Wei

Yes your assumption is right. The output is latched to the last set value.
If you are generating the pulse through the counter, setting the Idle state in Create Virtual Channel.vi doesnt help?

How to connect external trigger PCIe-1433?

I am having an issue getting the external trigger to work using a cameralink camera, a PCIe-1433 card and a signal generator. The signal generator is connected to the SMB connector on the 1433 card and is providing a 20 Hz signal with a 20ms pulse width at TTL voltages (0-4V). From memory, we are using the MAX software and under the Acquisition tab I have CC1 set to external, however the camera is not receiving this external trigger.
I've attached a rough diagram of our setup.
What could my issues be? My thoughts are:
1) Are there other settings in MAX I need to ensure? I know the SMB connector can be an input or an output. How can I make sure this is set to input?
2) My input signal is 0-4V which is TTL, but does the signal need to be 0-5V?
Any thoughts would be greatly appreciated. Thank you.

Hello tuckturn
Thank you very much for getting in touch with us.
1) In Measurement and Automation Explorer, the default is an input. You would need to use LabVIEW to change the SMB connector to be an output. Can you please show me a screenshot of your camera attributes in Measurement and Automation Explorer.
2) Where does this input signal come from? Do you have a 5V TTL compliant output to test this? Can you please provide me the specification for whatever device is outputting the voltage?
Thanks again.
Sincerely,
Greg S.

How do I auire data at every third pulse of an external trigger?

I need to aquire 2048 data points where each one is triggered by the third pulse of an external trigger (TTL). Currently I can aquire 2048 data points where each is triggered by every pulse of an external trigger but I need to be able to do this at every third trigger pulse. It seems that I can't do this simply by entering "2" into the "skip count" input of the "Additional Trig Parameters' input of the "AI Start" VI. My attempt is in the VI titled TriggerScanA.
Further more I will need to know the actual trigger scan rate for data analysis. This is also prooving difficult since even when I am triggering off every external trigger pulse the actual scan rate only returns zeros. My attempt is i
n the VI entitled TriggerScanB.
Thankyou.

Trigger_Scan_VI's.llb ‏211 KB

Greetings,
This sounds like an interesting application. I would suggest that you use your external pulse train as a scan clock, not as a start trigger. Furthermore, since you want to acquire data every third pulse, you will need to use one of your device's counters to divide-down this signal. To accomplish this task, you will need to configure the counter for pulse train generation with an external source - your external pulse train. You will then need to choose the correct "raw counts" to generate a pulse train with a frequency that is 1/3 of that of your external signal. I would suggest that you examine the example Generate Pulse Train (DAQ-STC).vi for this purpose. Now, you can perform a finite analog input acquisition of 2048 data points u
sing this pulse train as your scan clock. Finally, to determine the frequency of your scan clock, you will need to us your device's other counter to perform a frequency measurement of either pulse train.
I believe that this will be your best approach to accomplishing this task. Good luck with your application.

How to use an external trigger on an electrometer (KEITHLEY 6517A)

I'm really new using LABVIEW, so please, be patient with me...
I'm using a KEITHLEY electrometer to acquire data from a dosimeter. We are going to do some measurements on a pulsed source and before the pulse there's a trigger signal. I don't know the size of the trigger, I'll just know that when I start my measurements (in another lab) So I would like to implement a case were the user can decide the value of the external trigger, so this information goes to the eqipment before starting the measurement.
What I would like to know is... Someone can give me a hint on how to do that? I'm using GPIB and LABVIEW 7.1. and I already took all the 6517A libraries for labview.
Thank you all

The external trigger on a 6517 is a TTL signal. Any pulse higher than 3.4V will trigger it. You cannot program the threshold level.
You can set the delay programmatically with TRIG: DEL <n> command.

NI FPGA based programmed delay generator

Hello,
I am seeking for some suggestions from those working with degital delay generators.
We have a TTL trigger pulse train in which pulses are not equidistant in time (seperation between two pulses is not the same, it can be few ns to few microsecond), however, on average, the rate would be <2MHz. The pulses are 10-20ns width and 2.5V amplitude. From this, we want to generate 3-4 trigger pulse trains, which would be delayed with respect to the initial (input) pulse train by some arbitrary values (ns to few microsecond). However, the point is, we also want some trigger pulse trains in which only even number of triggers (or odd triggers) could be present. So in other words, we want to program the delay generator in such a way that one of the outputs could have only even or odd trigger pulses of the initial trigger pulse.
We first tried to look for available delay generator boxes and PCI delay generators. The problem is that they have insertion delay of typically 50ns or more. So in other words, the output triggers would be delayed from the initial trigger pulse not less than 50ns. Other, If we program them with labview, It seems the output response would be after few ms. These are quite large delays for us.
One such delay box manufecturing company suggested us to use FPGA based delay generators, as they say that these devices are having low insertion delays and quite fast programmable response. I looked in NI website for insertion delay and other parameters, but could not find these values. Pl. suggest whether FPGA based delay generators have low insertion time (<10-30ns) and if we program them, the output could be generated within ns response time?? As I am new with such devices, I would sppreciate if anyone could suggest about the possibilities to generated the delay sequences (even only or odd only triggers) using FPGA devices.
Thank you

MWM,
If you are planning to use the analog input I would recommend using the the 783x family of boards. They have analog inputs and they can provide the +/-10 v to the cRIO-9263 boards

Triggered pulse with variable delay using 6023E, getting started

I am having a hard time getting started with my PCI-6023E. My goal is to use it to create a programically controlled delay between the pulse I am inputting and the pulse I hope to output from the 6023E. I have installed the 6023E into a computer and am trying to trigger using a function generator. I am looking at the output using a scope. I think that maybe I have to "turn on" the output of a certain pin. I can't figure out which pins to connect where. I think I am supposed to use Counter Group Config.vi to control the delay, but i'm not sure. Any help or direction to helpful documents would be very much appreciated.
Thanks,
Emily

Hi Emily,
The PCI-6023E is supported by both the Traditional NI-DAQ driver and the NI-DAQmx driver. Since you are getting started with development of a new application, I would highly recommend the NI-DAQmx driver (right now I believe you are using Traditional NI-DAQ because of the Counter Group Config.vi). See the article here for information on the advantages of the NI-DAQmx driver.
Let's first take a look at the hardware level and what the 6023E is capable of:
The 6023E digital I/O lines are static, meaning that they either output a digital value or read a digital value at the instant the software function is called. Ideally, you would receive a digital trigger and specify in software a delay past the trigger to output the digital value from another line. However, the 6023E does not support triggers for digital tasks.
Any timing or delay will have to be taken care of on a software level. You could continually poll the digital line connected to your function generator to look for the trigger occurrence. When that trigger is detected, a software delay could be implemented before making a digital write to another line. If you choose to go the route of NI-DAQmx, there are a number of shipping examples included with the driver that could get you started. They can be found by going to Help>>Find Examples in LabVIEW to bring up the NI Example Finder. From there you would browse in the directory Hardware Input and Output>>DAQmx

Impulse trigger to create a time delay of x ms to perform an action for y ms

Hello all,
Here is what i'm trying to do:
I'm measuring an audio signal when a sound level is above a certain value Y (controllable) i need to wait a few ms (around 900ms) to get pass the main sound compound. Yhen i need to filter the next few ms (around 500ms) of data and do a FFT of that part of the filtered data only once until Y is reached again.
I can do all this with saved data but i'm struggling to do it as it occurs without saving the data.
I have everything in place i just need to know in general how to use an impulse trigger to a create time delay of x ms to perform an action for y ms.
Do you have any ideas how i can achieve this?
Thank you in advance,
Frederic.

Hi Frederic,
I've looked at your program and I have a few questions. What is the purpose of the Two While Loops that simply have a Case Structure that nothing in the false case and a Wait (ms) function in the true case? As it stands if these loops go into the false case then there is nothing to slow down the execution so the will try to run as fast as possible and not give the processor any time for other tasks which may explain why your computer goes so slow whilst this is running. This also applies to the While Loop where the false case says "If its not time to write the measurement file, do nothing."
I believe that what you want to look at is a Producer/Consumer(data) Pattern, where you have one loop that generates your data (producer), in this case reads in the sound data, and then a processing loop (consumer) that will do the Fat's and log data to a file etc.
More information about this can be found here: http://zone.ni.com/devzone/cda/tut/p/id/3023
Hopefully this helps you a bit. Let me know any questions you have.

ACE GigE - external trigger - example needed

Hello,
I have a CVS-1457RT with a Basler ACE GigE cam - I am having issues when I try to use a hardware trigger for the camera (thru the I/O connection on the camera)
I've been trying for a few days now, so I decided it was time to ask here
- have anyone used a similar setup, meaning the camera with external trigger? (controller is not the issues) and would it be possible to share the acquisition VI's?
best regards,
Henrik

Hi Ehlert,
Sorry you are having problems getting this to work!
There are a few things to keep in mind when configuring the triggers....
You will need to enable the trigger on the Ace camera to trigger the specific event (Frame Start) that you want to occur on the specific trigger signal. You might want to consult the Ace user manual for the specifics of doing this, as they have quite a number of options for how the trigger can be configured. Are you using the 1457RT to send the signal to the camera? If so you will then need to configure the 1457RT to send an appropriate trigger. We have some Vision RIO examples that show how to do this. Keep in mind that you also may be experiencing a hardware setup issue. If you are using the isolated outputs on the CVS you will need to provide external power for the outputs to work. It is probably helpful to examine your physical trigger line with a scope and verify thaty the trigger signal is going when you expect, allowing you to isolate which end is not configured appropriately.
In general, assuming your trigger signal to the camera is working, setting the camera up for triggering is pretty simple:
-Set Trigger Selector to "Frame Start" (to set context for the other trigger features)
-Set Trigger Source to "Line1" (only option on Ace GigE)
-Set Trigger Mode to "On"
-Set other related features (rising/falling edge, delay, ...)

Externally trigger binned counting

Hi,
I have a PCI-6221 and am trying to achieve the following. I've tried searching and found similar questions, but nothing exactly the same, so apologies if I have overlooked a previous answer.
What I would like to do is count total pulses per 100 µs for some fixed period of time, say 100 ms. The start of the 100 ms total measurement period should be triggered by an external signal which is much slower, e.g. 1Hz This is as I need to sum multiple mesurement events as follows, where the time bins given are times after the trigger signal and each measurement is triggered by the external signal.
Measurement     0-100µs 100-200µs    200-300µs etc.
     1                    2                1                0
     2                    1                2                1
     3                    2                1                1
     4                    0                1                0
total    5    5                2
If I could get the rolling total for each measurement that would also be fine, I can subtract each time bin from the previous in software. The previous example using this method would therefore be:
Measurement     0-100µs 100-200µs    200-300µs etc.
     1                    2                3                3
     2                    1                3                4
     3                    2                3                4
     4                    0                1                1
total    5    10              12
I have looked at previous answers such as http://forums.ni.com/ni/board/message?board.id=40&message.id=2056&query.id=1096458#M2056 and whilst I converted that to a finite number of measurements OK, I couldn't work out how to set it to digitally trigger without errors. I'm using LabView 7.1.
Thanks very much, I hope that this was clear.
Alex

I haven't fully fleshed out this idea, but here it is in a think-out-loud form.
I'm assuming you don't have clocked analog output in your app, and will lean on using an AO task solely for its clock.
Here's the idea:
1. One of your counters is set as a retriggerable single pulse generator. Let's say it's CTR0. Use the external ~1Hz signal as its trigger, and set it up to generate a single pulse with a 100 msec high time and a minimal low time. You'll need a DAQmx property node to make it retriggerable.
2. Configure an AO task to generate at 10 kHz, corresponding to your 100 microsec bins. Configure it to be pause triggered by the output of CTR0. Thus, the AO generates samples at 10 kHz, but only while CTR0 output is high (for 100 msec). You'll have to write a buffer of analog values to generate, but it can just be an array full of 0 voltage, and you don't have to wire that output to anything either.
3. Configure your other counter, CTR1, for period measurement. This may be tricky to configure with DAQmx property nodes, but ultimately you'll need to treat your pulses of interest as the timebase for the measurement while using the AO sample clock as the signal to be measured.   That sounds backwards, but the effect will be to store the number of your pulses of interest that occur between AO clock edges. You will need to research "duplicate count prevention" to make sure that 0 values get buffered properly.
I *think* that sort of arrangement could work. About every second, you get an external trigger. That trigger causes CTR0 to generate a single pulse with a 100 msec high time. Your AO task generates a clock pulse every 100 microsec, but only during the 100 msec when CTR0 is high. Each of those AO clock pulses buffers a value for your CTR1 period measurement. This should produce a measurement buffer like the first one you listed.
4. (Simpler Alternative) Configure CTR1 for simple counting. Use DAQmx Timing.vi to specify the use of the AO Sample clock, and specify your external pulses of interest as the signal to measure. By default, LabVIEW will expect to see those pulses at CTR1's default SOURCE pin. This arrangement should produce a measurement buffer like the second one you listed, though you may still need to research "duplicate count prevention" to make sure that gets set up right.
5. I can't help but think there's another way to do this without the AO stuff, but nothing's coming to me now.
