Setting up the Arbitrary waveform generator in python
Setting up the Arbitrary waveform generator in python
Hi,
I'm using a PicoScope 5442D with picoSDK and python, and I've been trying to use the AWG but haven't managed to make it work so far, as it only generates noise.
In the code below, I try to generate a sinusoidal signal starting off the examples provided. To check the generated signal, I've reused the code from the example "ps5000BlockExample"
If I try to use the Built-In signal generator as in the following example, the signal is generated correctly.
I've been searching for a while but still not found a way to make it work, so any help would be appreciated.
