Hello,
I'm using the RP_REMOTE_ACQUIRE program von Nils Roos to get Data out of both Channels. When I try to measure a 20kHz square-wave signal from a function generator I get distorted pulse edges, which I don’t get with the oscilloscope app.
Has anyone similar problems or any Idea how to fix it?
For my application I need to measure two channels for 10 ms at the same time.

I am not familiar with Nilses code, however from symptoms that you describe, it looks like Nilses FPGA image does not include a filter that compensates for analog ADC line distortions, that original Red PItaya FPGA image includes.

Yes thanks, I found this link https://forum.redpitaya.com/viewtopic.p ... 8&start=10.
Then I had to activate those Filter in the RP_REMOTE_ACQUIRE program at HV settings and now it works.
