How can we generate a pulse train with variable inster pulse delays?

I want to generate a pulse train with random inter pulse delays (100us-10000us) and the pulse width would be 50-100us. I programmed for single pulse generation using counter cfg,a for loop contaning set attribute parameters pulse spec 1 and pulse spec 2. I changed the pulse spec 1 value in every cycle
This program is generating the pulses but not the exact values in the sense the some times the delays are more than 10 msec. As per the program the delay should be maximum 10 msec. please help me ASAP.
thanks

Hey Thota,
I would suggest to take a look at the example program linked below. It shows how to change pulse specs on the fly. You have to be make sure you are ignoring a certain error when doing this.

How to continuously generate a pulse train with variable frequency

Dear all,
I am trying to use NI-USB 6259(BNC) to send Pulse signals to conduct position control of a servo motor with labview. The position control of servo motor follows these rules:
The number of the pulse train determines how many degrees the motor rotate ;( e.g. the angular position of motor)
The frequency of pulses determines how fast the motor rotate; (e.g. the speed of motor rotating)
The digital determines the direction of rotation of motor (e.g. clockwise or counterclockwise)
My question comes when I need to continuously generate a finite plus train signal in a period of time. Below is a sample:
Time(s)
Number of pulses
Direction of rotation
(1 is clockwise, 0 is counterclockwise)
Frequency
0-1
923

923hz
1-2
3540

8-9
1513
1
1513hz
9-10
570

570hz
Here is the explanation of this table, the motor keeps rotating in clockwise direction during 0~1s. When the time reaches 1s, the motor just complete the rotation of 923 pulse signals. And then the motor starts to rotate in counterclockwise direction during 1s~2s. When the time reaches 2s, the motor just complete the rotation of 3540 pulse signals. So we can see that the rotating speed of motor in 0~1s is different from the speed in 1s~2s. Namely, the frequency of pulse signal in 0~1s is different from the frequency in 1s~2s.
I have already use the counter output of DAQmx, it just can generate pulse signal with certain numbers and certain frequency in one time. The attachment is the vi which can generate a finite digital pulse train from a counter output channel and the frequency, duty cycle, Initial delay, and Idle state are all configurable.
How can I continuously generate a series of pulse train with varying numbers and frequencies during a certain period of time.
Thank you very much for your help!

Hi aacuna,
Thank you for your reply!
I already checked that article. The frequency in that Vi can change dynamically, but the method of adjusting the frequency is ‘manual’ .Below is the front panel of that Vi. When the Vi is running we can change the frequency by press the button.

Finite pulse train with variable pulse widths

Greetings LabVIEW developers,
Does anyone have code that can show me how to use E-series counters to generate a finite pulse train where the individual pulse widths vary? I need to generate a series of 20 pulses with the high time for each pulse randomly varying between 50 and 1000 microseconds. The low time for each pulse needs to be constant (around 50 microseconds).
Thanks,
Ryan Wright

Ryan,
Sorry, but this isn't possible with the counter/timers. I've been wanting this capability myself for about 6 years now.
Personally, I think it's an unfortunate "hole" in product capability. The other major data acq hw allows you to capture and later replicate a signal of interest. You can capture an analog waveform with AI and later play it back with AO. You can capture a digital pattern and later play it back with timed DIO. You can capture buffered semi-periods with a counter -- but you can't play play them back later. So for your app, you'll need to generate the variable freq using timed DIO. The new M-series boards ought to work for this, or a dedicated high-speed digital board.
There's another product that I think is even better for timed DIO though and it's put out by one of NI's "Alliance partners" -- Viewpoint systems. Here's an example of why I like it. Let's say you need to generate 20 pulses within 60 seconds. The times of the pulses need to be precise to within 1 usec, and they have no common divisors. The NI method will require you to use an update rate of 1 MHz and you'll create a buffer of 60 MB to represent the digital pattern at every usec. The Viewpoint method needs a buffer of 40 entries. Each entry is a combination of a timestamp and a pattern to generate at that timestamp. That pattern will just stay there until the next defined timestamp. So all you do is define the digital pattern at the instants when one or more bits will change. It works analogously for digital input - if you capture with 1 usec resolution for 1 minute but there are only 20 pulses (40 digital transitions), you only capture the 40 relevant timestamps & patterns instead of a full 60 MB.
If interested, look for the PCI-DIO64 at Viewpoint's website.

Please, I need help - How can I generate a text file with Word format?

Hello friends at www.oracle.com ,
is it possible for me to create a text file - that is, with TEXT_IO.fopen, and so on - that's already formatted as a Word document?
We have a Forms program here, where it's needed to generate a text file with .RTF format, 8 centimeters margin, Times New Roman font, with size 7.
Best regards,
Franklin Goncalves Jr.

Hello Shay,
sincere thanks for your answer. And, to answer your last question, I'm using client-server model.
Since I couldn't create this .RTF file by using built-ins like TEXT_IO, I tried to generate an .RTF file using Reports, passing the parameters DESTYPE, DESNAME and DESFORMAT, as shown below.
add_parameter (pl_id, 'DESTYPE', text_parameter, 'FILE');
add_parameter (pl_id, 'DESNAME', text_parameter, 'c:\franklin.rtf');
add_parameter (pl_id, 'DESFORMAT', text_parameter, 'RTF');
However, the just generated .RTF file is uncomprehensible. After opening the file at Microsoft Word, I can see the following message at the top of file:
This file was created by Oracle Reports. Please view this document in Page Layout mode.
... and informations doesn't appear as desired.
If I can't generate such text format by using TEXT_IO, and if generating an .RTF file through Reports shows me an incomprehensible result, how can I export the selected result to an .RTF file?
When Reports is opened, choosing Generate to file -> RTF doesn't export anything.
Thanks, and best regards,
Franklin Goncalves Jr.

How can I generate a map file with LabVIEW?

We wish to use a product which inserts code into our executable to prevent tampering with it by crackers. The program, however, takes the executable file, as well as the map file (which is commonly generated by c++ compilers) and uses the map file to determine where in the exe the critical routines that need protection are at. I can not, however, determine how to create such a map file for a LabVIEW generated executable. Is there a special build option I need to invoke?

Yes, I'm familar with NI's licensing technology, having talked with someone (you, Dennis, I believe) about it before. The problem we have is our software is sold to factories in China where there are no internet connections. We have a physical key 'dongle' which must be present in order for the executable to be willing to run. However, it appears that people are taking the executable which LabVIEW creates and they are editing it, probably by using a a debugger and tracing to the the code which checks for the dongles presence and bypassing it. To my knoweledge, NI's products don't do anything to prevent this, right?
We found a company which sells a product that encryptes, checksums, etc... an executable file, but it needs to know the layout of functions in the exe in order to determine which areas to focus the obfuscation on. They were sort of matter of fact when they said it needs the exe and the map file, as if they expected any language which produced an exe could produce a map file.

How can I generate email to client with Cap 6?

Hello,
This may be a novice question but here goes... I'm using Captivate 6 to create a test (quiz). I specified that I want it to send an email to the client under the Pass or Fail Quiz settings but all it does is open the test-taker's default email system with the client's email address in the To: field. I need it to send an email notification (preferably just when test-takers passes) to the client without test-taker intervention. Any ideas or suggestions? I'm guessing there's some javascript involved...
Thanks,
DAS

Hi DAS,
If you are looking to report the Quiz Results, the option is not available in Captivate 6 to send email with quiz results.
If you want you can assign a send email instruction on Pass/Fail option, but that would not add any quiz detail, it would launch a e-mail body (configured with Outlook as e-mail client) and user can type in their content.
You may use a small action which would shoot email ast : [email protected]?subject="Hello" but you may not be able to add more info.
You may look for a widget that might achieve it for you.
Thanks,

How can I generate synchronized pulse trains with 6602?

Hi,
I would like to generate multiple pulse trains with different frequencies with the 6602 TIO card. Currently I am able to generate pulse trains with different frequencies. But is there any way to synchronize all the pulse trains? For example, I'd like to have all pulse trains with their first low-to-high at the same moment.
Thanks!
Dan

Dan,
Absolutely, the NI-TIO chip on the PCI-6602 supports a start trigger. If you configure all of the counters that are generating a pulse train to use this start trigger, they will be synchronized. The example Generate Pulse Train - Start Trig (NI-TIO).vi demonstrates this process for one counter. In LabVIEW 7, this example can be found in the following location:
Examples >> Hardware Input and Output >> Traditional DAQ >> Counters >> NI-TIO
You will need to add code for the other counters, but this example should give you the general idea. Furthermore, this example demonstrates how you can use one of the digital lines to generate the start trigger.
Good luck with your application.

How to generate a pulse train with different pulse width and delay?

How to generate a triggered pulse train with different pulse width. for example, after each trigger signal, let's say 2 ms, then the counter output a pulse with pulsewidth of 1 ms, and then after 3 ms delay after the first pulse, the second pulse was generated with a pulse width of 4 ms. Next cycle when the trigger signal comes, the same two pulses will be generated and so on. Is it possible to achieve this by using 6601 counter card? and if yes, how to achieve this? Thanks!

Unfortunately you can not create a hardware timed pulse train with different widths on each pulse from a counter. Whilst it can be changed on the fly using software, since you require a hardware triggered signal getting the software involved will not give a huge amount of accuracy when the pulse will actually change.
So in short you can't use your 6601 card (or a counter timer) to achieve this
There are three possible Alternative solutions
1 You could use a high speed digital IO device such as the (6533/34) to generate your variable signal which would require setting up the pulse train as a series of states based around the burst transmission mode where the clock would give you your specific timing.
2 A timed analogy output (for example on a MIO card with a clock (PCI-6220 / 62xx), i.e. Not the 6704 style static analogy output cards)
3 A high speed digital waveform card such as the (, 656x , 655x, 654x, 6534, 6533 (http://www.ni.com/modularinstruments/find_right.htm) ) this could then be scripted to work with your triggering and also there is a digital waveform editor which will enable you to set up the pattern you wish to generate (http://sine.ni.com/nips/cds/view/p/lang/en/nid/13555)
Hope that helps

How to generate sequence of pulse trains with DAQmx?

I need to generate a sequence of pulse trains with DAQmx (the card I have is a PXI-6229 card). As an example:
- 10'000 pulses at 20kHz every 5 seconds with an initial offset of 2 seconds (let's say 10 pulse trains in total).
If I use the CreateVirtualChannel.vi in "CO pulse ticks" mode, I can only specificy offset, high ticks and low ticks, but not that the sequence of pulses should be repeated after some time.
Now I thought that I could solve this problem if it were possible to multiply two counter outputs: the first counter would generate the pulses (continuously) whereas the second one would switch between low and high on a slower timescale in order to gate the first counter, thereby providing an initial offset and the "off" phases between the pulse trains.
Is it somehow possible to multiply two outputs with DAQmx and the card I have? Or is there another solution to the problem?
Thanks a lot in advance for any hints!

Hi dlanger,
what you want to do requires a little bit more work.
First look at the example "Gen Dig Pulse Train-Continuous.vi" from the LV example finder.
This example generates a continuous* pulse train. As you see, you need a sample clock VI for setting the sample mode.
* NOTE: Generating a finite pulse train with a M-series card requires 2 counter.
With a pause trigger (DAQmx trigger property node) you can gate the output of that counter.
Now you have to generate a gate-signal with the the 2nd counter. That means, only if Ctr1-out is high Ctr0-out outputs the 20 kHz-signal.
Maybe you have to adjust the times in my example a bit.
Unfortunately there is just one "small" problem: "let's say 10 pulse trains in total"
This is not possible, because a 3rd counter would be necessary (*).
As a workaround you can modify the while-loop that both tasks are cleared after 50s. This is not brilliant, but should work fine for you.
A more sophisticated way is to perform a correlated DIO. So you can generate custom pattern for multiple outputs.
A good example can you find here:

http://decibel.ni.com/content/docs/DOC-8473
or here:

Hope this helps.

HTML to PDF with Java, using OpenOffice.org - example here: [http://www.dancrintea.ro/html-to-pdf/|http://www.dancrintea.ro/html-to-pdf/]
You can use OpenOffice.org, running as a server and command it remotely for document convertion.
Besides HTML to PDF, there are also possible other convertions:
doc --> pdf, html, txt, rtf
xls --> pdf, html, csv
ppt --> pdf, swf
Code example:
import officetools.OfficeFile; // this is my tools package
FileInputStream fis = new FileInputStream(new File("c:/test.html"));
FileOutputStream fos = new FileOutputStream(new File("c:/test.pdf"));
// suppose OpenOffice.org runs on localhost, port 8100
OfficeFile f = new OfficeFile(fis,"localhost","8100", true);
f.convert(fos,"pdf");

How can I generate a html page in a servlet-applet connection?

Hello, I have an applet which contains an ok button, when I click this button, I need that servlet generate an html page and view it in browser. How can I do this?
Thanks

But with this method only is possible I think open a page web, and if it is possible call url of the servlet, you generate other request and response object (other call to method doGet or doPost because ShowDocument needs parameter url), so the previously request when I click button ok it's no the same and how I obtain the prinwriter from first request, showDocument don't obtain html page from printwriter.

How can we generate proxies?
