How to synchronize NI PXI-6534 and NI PXI-6259?

Hi,
I am trying to output a continuous analog waveform (sine, dc, ramp, etc) using an AIO card (6259) and a DO pulse (using the PXI DIO 6534 card) with a customizable Duty cycle in each period of the AO signal. I need them to be in sync. Both cards reside in the NI PXI-1042Q chassis. I am using this solution as an example but can't get it work.
Also, my DO card cannot write high-frequency pulses on one line - I should instead use the entire port. It also cannot produce CO pulses.
Can anyone help with a simple vi? What is the correct way to synchronize these two cards (I am a beginner in LV) in one crate?
Thanks in advance,
~Paul

Hi Paul,
I see that has been a while since there were no activity here.
Did you manage to synchronize them?
Basically, you can synchronize them by using the PXI backplane clock. A very nice tutorial can be found at the following link http://www.ni.com/white-paper/11369/en

Can't configure a SCXI chassis (PXI-1010) with a PXI-8176 and a PXI-6052E.

I have a PXI-1010 chassis with a PXI-8176 running Windows 2000. In the rightmost PXI slot, I have a PXI-6052E. The remaining PXI slots are either empty or have misc. modules in them. I have a SCXI-1520 in the leftmost SCXI slot.
I am trying to get MAX to recognize my SCXI chassis with the SCXI-1520. When I try to add the SCXI chassis in MAX by right-clicking "Devices and Interfaces" or "NI-DAQmx", I leave the communication mode to communicate on the PXI backplane, choose SCXI slot zero, and find that the communication device field is greyed out where I want to choose the PXI-6052E. For some reason,the wizard used to add an SCXI chassis does not see my PXI-6052E pluged in to the leftmost sl
ot. Strangely, MAX does see the PXI-6052E in the "Devices and Interfaces" tree. I verified that the 6052E is working correctly. I also verified that the pxisys.ini file is in the WINNT directory. What is the problem?

I am first trying to install the SCXI chassis using the SCXI 1520 user manual. I put a PXI-6052E in the right-most PXI slot and the SCXI 1520 in a SCXI slot. On page 1-12 of the SCXI-1520 user manual, it instructs me to power up the chassis, right-click on MAX "devices and interfaces", choose the correct chassis, and click finish. The problem is, after I click finish, a window appears that forces me to choose a DAQ device. The SCXI chassis doesn't configure correctly because the wizard doesn't see the PXI-6052E.

How to synchronize multiple, unorganized audio- and video clips

I'm editing a video with audio recorded by an external recorder.
I've been given a lot of unorganized files and I wonder if there's a quick way to synchronize them all without knowing which audio- and video file that fit together.

I've been pretty amazed by how well the synchronize clips command works. You might take a chance and select all of your audio/video files at once, right click and choose Synchronize Clips.

How to synchronize the signal sending and data acquiring process dynamically with one DAQ_Urgent

Dear Sir,
I am using one DAQ card to send a modulation signal (which is a signal summed by a low frequency saw tooth and high frequency sin signal) to the laser controller, and acquire voltage signal from another instrument (It is in a same measurement system with the laser controller)?
I would like these two process happening at the same time.
In the attachment, there are two parts, one of them is signal generating program, the other one is data acquiring program, how to do like this: when I press"run", first the modulation will be sent to the laser controller immediately, and at the same time, the acquiring program starts as well...
In addition, I think my program is not complete, could you please help me check if there are any other problems with it?
Thank you very much.. and appreciate your quick reply in advance.
Best regards,
Memorysun

Hi Memorysun,
Thank you for your post and welcome to the forums.
From your description what you want to achieve is:
Write data to a Analog Output channel that is then recieved by the Laser
Acquire (read) data from using an Analog Input channel (output from Laser/Instrument)
This can be achieved using a single VI with 2 seperate DAQ tasks, one the "Continuously Writes" to the Laser and the other that "Continuously Reads" from the Laser/Instrument. Can I recommend the following examples that can be found in the NI Example Finder (Help>>Find Examples>>Hardware Input and Output>>DAQmx):
"Cont Gen Voltage Wfm-Int Clk.vi" (for continuous writing)
"Cont Acq&Graph Voltage-Int Clk.vi" (for continuous acquisition)
The code from within both these VI's can be placed in a single VI therefore achieving the desired functionality.
Many Thanks
Jamie,
They would be better served with an example that routes the AO hardware sample clock to the source of an externally clocked AI.
Using the examples you posted will still leave them with the challenge of trying to alligh stimulus with response.

Are the PXI-1002 and the PXI-1031 chasses mechanically interchangeable?

I see from the specification sheets that they are exactly the same size. However, do they have the same locations for mounting holes, protrusions for switches, power cord location, etc?

Sudhir,
Yes, the PXI-1031 chassis is a direct mechanical replacement for the PXI-1002. All mechanical features of the PXI-1031 should line up with those of the PXI-1002.
Please post a reply if you have any additional questions about the PXI-1031.

How to synchronize audio track and video when transmitting by RTP

since the audio stream and video stream are transmitted separately on the network even if in a merged data, how to synchronize the audio stream and video stream at the receiving end ?

camelstrike wrote:
Hi everyone!
I've tried to make one of the processors, processor1, control the other processor, processor2, with processor1.addController(processor2) but I get a
javax.media.IncompatibleTimeBaseException. I need to synchronize audio and video rtp-streams because they are sometimes completely out of sync.
In JMF API Guide I've read:
"2. Determine which Player object's time base is going to be used to drive
the other Player objects and set the time base for the synchronized
Player objects. Not all Player objects can assume a new time base.
For example, if one of the Player objects you want to synchronize has
a *push-data-source*, that Player object's time base must be used to
drive the other Player objects."
I'm using a custom AVReceive3 to receive rtp-streams and then I create processors for the incoming stream's datasource's, and they are ALL PushBufferDataSource's.
Does this mean I can't synchronize these. If so is there any way I can change them into Pull...DataSources ?The RTP packets are timestamped when they leave, and they are played in order. You can't change the timebase on an RTP stream because, for all intensive purposes, it's "live" data. It plays at the speed the transmitting RTP server wants it to play, and it never gets behind because it drops out of order and old data packets.
If your RTP streams aren't synced correctly on the receiving end, it means they aren't being synced on the transmitting end...so you should look into the other side of the equation.

How to acquire data through multiple channels in parallel using PXI 6070 E, PXI 4071 and LabVIEW?

Hi,
I am using NI LabVIEW, NI PXI 4071, and NI PXI 6070E to measure current through a variable resistance. Now, I am using one channel from SCB-68, but I want to add another channel in parallel so that I can have two resistors instead of one that I cam measure current through them.
I have attached a Pdf file showing the setup for hardware in use and LabVIEW code also.
Can anyone look at these files and give me guide lines or ideas that can help me resolving this issue, please.
Thanks in advance.
Best Regards,
Shaheen.

Your 4071 can only do one measurement at a time. Your DAQ cannot measure resistance either nor has it got any analogue inputs.
However, you could use a multiplexer and multiplex your 4071 DMM. This wont give you simultaneous measurements but can acquire data one after the other, the speed is obviously dependent on the multiplexer you choose!
Hope this helps.

How to synchronize two fpga DIO?

Hi!
I am using two FPGA 7962R (flexrio) with each 6581 terminal board in PXIe-1082 chassis. My problem is how to synchronize two 7962R digital output with PXIe-1082 chassis backplane signal Dstar* or Clk10 or DAQ signal.
Actually I tried the synchronization with one DAQ counter clock (confering 'Gen Dig Pulse Train-Finite_NI. vi') , and get the signal PXI-Trig0 by source terminal and target terminal connection, but that one does not work properly. Especially, one trigger signal in HOST to set the starting point of each FPGA (7962R), make error by depending on the trigger signal value(Hz value and Timed loop clock in FPGA vi). It was very tricky and not reliable. (I am attaching figure files as explaining the situation)
My aim is simply to use two FPGA 7962R Digital output as one FPGA, for controling X-axis, Y-axis with each FPGA, while able to change each FPGA (X-axis, Y axis) digital output value. Because the synchronization is not correct, X,Y axis control with Two FPGA currently is out of target if I use simply while-loop design in HOST and timed-loop design in FPGA vi. What is correct design to synchronize the two FPGA 7962R without using PFI line, only with PXIe-1082 chassis backplane signal and able to change the digital output value? Please let me know any idea for HOST vi, FPGA vi programming.
Many Thanks

Using PXI-6682(H) in PXI Express chassis to replace backplane clock

I have a PXI-6682H in a PXIe-1075 which I use for event timestamping. I also have a PXIe-6672 card in the timing slot.
I would like to replace the 10 MHz backplane clock to use the 6682 as a GPS disciplined oscillator and synchronize multiple PXI chasses.
I understand from the block diagram in the manual that the PXI-6682H does not possess the connection to directly replace the backplane clock as the PXI-6682 does in a PXI chassis.
Is there any way for me to replace this clock? Perhaps using an external connection? If so could you briefly explain how this would work and what software steps would be required?

Hello Gregoryng,
It might work since the PXIe-6672 and the PXIe-6674T are both timing and synchronization modules, but the best option would be the PXIe-6674T, which is able to work with other protocols such as GPS while the other cannot. It seems that in the video they use GPS.
I think the PXIe-6672 will not work for this with the PXI-6682H, but you can give it a try.
The one in the video seems to be a PXIe-6674T.
Regards.
Ernesto.

How to synchronize sampling on PXIe-5162

Hi, I need to characterize phase and amplitude imbalance of two quadrature signals from a 14bit TxDAC. I selected two 5162 modules to do the job. The signals can have a frequency of up to 1.2GHz..
Is PXIe-5162 capable of doing this job?
The plan was to record a long sample of the signals and then do the processing in ie. Matlab.
I am facing a few problems. Is it possible to synchronize sampling of all channels on one 5162 module, and how to synchronize sampling of 2 x 5162 modules with enough accuracy to have a phase resolution below 1deg?
Are there any examples of how to synchronize sampling of multiple channels/modules in LabView ?
Can the phase and amplitude measurement be done directly in LabView without involving Matlab?

Hi Robert,
Did you already read some white paper and KB about synchronization using LabVIEW?
http://www.ni.com/white-paper/11369/en/
http://www.ni.com/white-paper/4322/en/
You can find some other white papers on ni.com. I think this will be a good start before doing something else.
You also can search in the LabVIEW examples.
Here some information about the measurement of the phase and the amplitude:

How to synchronize NI-Scope and DAQ

I use a PXI-1042 System with a PXI-5124 Ni-Scope Card and a PXI-6120
with traditional DAQ controlled by a PC running WinXP and LabView 7.0
The intention of this setup is to make synchronized acquisition with
both cards with different sample rates. For the sake of an example let's
assume the NI-Scope runs at 100MS/s and the DAQ (6120) with 100kS/s. The Trigger is generated by
analog triggering of the 6120. I'm looking for a solution to garanty
that for a STOP trigger with post-trigger scans the last sample of the
6120 coincides in time with the last sample of the NI-Scope 5124 card.
Or to put it in more general terms a way to identify which of the 1000
Samples the 5124 Card takes in the sample interval of the 6120
coincides with the respective sample of the 6120 ? The point is to have
a time resolution (for phase difference measurements) better than that
given by the samplerate of the PXI-6120.

Here you can find an example that shows how to synchronize a DAQ-Device with a Scope-card:

How to synchronize two pxi ni5112?

Now in my system there are 2 PXI NI5112.Both NI5112 have the same configuration and all their inputs are connected to the same pulse signal source(10Hz).Both NI5112 use analog edge triggering and the trigering source is the channel 0.So all the NI5112s should be trigered at the same time.However,when I fetch the waveform with the function niScope_Fetch from each NI5112 in sequence,I find that the values of wfmInfo.absoluteInitialX vary a lot(10-70ms).why?"
Judging from the last paragraphs On page 2-11 of NI5112 User Manual,PXI NI5112 can be synchronized by the system reference clock.But how to do this?

It will depend on what you are programming the NI 5112 device with.
If you are using LabVIEW, you can use the example program attached below. In it, it will show you how this is done.
If you are using VB, VC++ or CVI, you can look at one of the NI 5112 shipping examples that are installed on your computer. These are located in the VXIPNP folder. For example, the VC++ example would be located here:
C:\VXIpnp\WinNT\NISCOPE\Examples\c\MStudioC++\5112Sync
These examples will show you how to synchronize the two digitizers.
Let me know if you have any questions about these examples.
