I am trying to get started with my PicoScope2203 device in Labview. I've tried following links to examples on this site, but there is nothing to be found. I also tried a custom install so I could see examples, but nothing there either. I have LabView 6.1, 7.1, 8.0, 8.2 and 8.5 installed on my PC, so just about any version will work.

The Measurement and Automation Explorer hasn't been helpful in accessing my device, so I just need help getting started here. Does anyone know how I could go about accessing my PicoScope2203 through LabView? The PicoScope 6 program is intuitive and easy to use, but I would like to use LabView so I can incorporate several other measurement instruments for testing.

Thanks

For more clarification on what I'm looking for, it is a LabVIEW front panel that is basically like a normal O-scope. I've downloaded some of the PS300 stuff in here and replaced the function calls with PS200.dll instead. Problem is, the functions between PS3000.dll and PS2000.dll are different and whenever I make changes and try to run the VI, I get an error and LabVIEW closes all windows.

I've managed (I think) to get channel A and B to acquire a signal, but I can't seem to get the signal generator to output a signal. Is there a VI available that allows me to output a signal from the sig gen while simultaneously reading a signal on channel A and B. The ability to add measurements would be nice too.

If no one has these VIs, does anyone have or know which document explains the functions in the PS2000.dll file? Something like a programmers reference guide that explains what "ps2000_set_sig_gen_arbitrary" means and what it does.

Thanks.

Hello!!! Is there anybody out there? I still cannot get my Picoscope 2203 to work in LabVIEW. I found examples and programmers reference in PicoScope 5 (not PicoScope 6, which came with the device), but nothing works correctly for me. The examples (PS2000.VI) are not recognized by LabVIEW and none of the O-Scope or Sig Gen capabilities are working the way I have programmed.

When I run the O-scope and input a DC signal (2 Volts) I can see a momentary spike on the front panel graph, but it soon settles to 0 volts. When I run the Sig Gen (attempting a 2 V DC output) and measure the output with a DMM, there is nothing but a mere 18 mV present. I have tried to refer to the 'ps2000pg.en.pdf' to program these VIs, but I am not having success.

I'll attach my VIs and hopefully someone here can help me figure out what I'm doing wrong. All I want is to write a LabVIEW program that will allow me to have the same capabilities that I can have while running 'PicoScope 6.'

Dbutz57,

Refer to the email I just sent for your code. For others looking for example code for the PS2000 series I have attached an example showing how to collect data from the scope and how to use the built in signal generator. If anyone has questions on how to use a certain function feel free to ask here on the forum.

Dear Richard,

Could you please send the signal gennerator VI for PS3000 in Labview 7.0 for me as well.

Regards,

Jav

Jav,

Refer to the attached file for the signal generator for the PS320x series scopes. Simply add these items to your existing block and wire the handle to this function. For exact information on the call refer to your user manual.
