Hello Hitesh,
Progress is being made! I am learning a little bit as well. I am getting an error 5003. Does an error code chart exist in the 5000a programmers guide?

I have included screenshots of ps5000aSigGenFrequencyToPhase parameters and the ps5000aOpenUnit.

Thanks.

Re: 5442B to generate single instance of waveform from CSV f

Hi Hitesh,

I made the changes. I am still getting the error out of 1097. the return value of return type is 12. This value seems inaccurate. Any thoughts?

This is the only VI used. I have included screenshots of the Call Function Library Node.

Re: 5442B to generate single instance of waveform from CSV f

Good afternoon all,
On page 84 of the 5000 Series Programmer's Guide the formula given is
outputFrequency = dacFrequency × ( deltaPhase / phaseAccumulator Size) ×
( awgBufferSize / arbitraryWaveformSize)

Is the dacFrequency constant regardless of the desired output frequency?

Thanks,

Re: 5442B to generate single instance of waveform from CSV f

Great!
The AWG is spitting out one instance of the waveform. However in reality the whole waveform is 9.4 milliseconds long. The waveform I am getting out is roughly 3.2 milliseconds. The shape is accurate just not the timing. Would someone please point me in the correct direction?

5442B to generate single instance of waveform from CSV file

Hello everyone, I am seeking to generate a single pass of a waveform in the AWG mode. I have a saved csv file of my waveform. My file has 2500 points. I want it to run a single instance with LabVIEW and be done. I have tried to use the 5000 series example with no success. What setting am I missing f...

Re: PicoScope5000a multiple channel

I have not gotten any responses to my question. If requested I will post my question under a different topic. I did manage to find a way to display all four channels. I changed the “Number of channels” under “Device Info” in the “PicoScope5000aGetBlock.vi” to “4” My nagging question is why isn’t or ...

Re: PicoScope5000a multiple channel

Sorry I had the files labeled backwards. Also I realize this is not for steaming. Nonetheless I am unable to get channels C and D to display. Any suggestions after looking at the real block diagram?

PicoScope5000a multiple channel

BLOCK DIAGRAM SCOPE VI.PNG
I have a PicoScope 5442B. I have been working to operate all the 4 channels in LabVIEW, but I could only operate
channel A and B; however channel C and D gave me straight line at "0" my block diagram is attached as png files.

Re: reset the connection of the Pico

Would the handle be the same for a Picoscope 5442B?
