How to generate an atrbitrary waveform python script with NiRFSG?

[markusmat97]

Hi
i found few examples here.https://github.com/ni/grpc-device/tree/main/examples/nirfsg.Would some can tell me if i want to generate an arbitrary waveform.How can i build a python script for this?
Do you have any guide to build python script?

The examples here in the grpc-device repo are intended only to familiarize you with how to interact with the driver via gRPC. The entry points, though, largely mirror the C entry points, so it should generally be straightforward for you to adapt an example that you find elsewhere, like those mentioned here or here.

For example, after installing NI-RFSG, I found a C# example for arbitrary waveform generation here:
C:\Users\Public\Documents\National Instruments\NI-RFSG\Examples\VS2012\ArbitraryWaveforms\ArbitraryWaveformGeneration\cs
In the MainForm.cs file there, there's a StartGeneration method that you could mimic.

It's usually going to be easiest to translate from the CVI example, though, if you install CVI support. I found the corresponding example here:
C:\Users\Public\Documents\National Instruments\CVI\samples\niRFSG\ArbitraryWaveforms\ArbitraryWaveformGeneration\

thank you for the reply.
i tried to find the CVI example but there was no CVI folder in my C:\Users\Public\Documents\National Instruments
How to get that?

You have to check the box to install CVI support when you install (or modify ⚙️) NI-RFSG. But you might have to have CVI installed for that option to show up, I'm not actually sure.

Hi @markusmat97,

I just uploaded a script that shows this:
