Hi,
Using a AD3250 I'm recording the output of out1 on in1 and notice glitches in the recorded signal. I attached a modified version of AnalogOutIn_PlayRecord.py to reproduce the issue.
Steps to reproduce :
Connect WaveGenOutch1 to Osciloscope Channel1
AD Pro 3250 connected with USB directly to laptop
Run attached ReproduceGlitchesInRecording.py
Check the 3dr plot, which is the diff of the recorded signal.
Observations:
When connecting Osciloscope Channel1 to an external signal generator I do not see these glitches.
Glitches seem to be 2^18 = 262.144 samples apart.
Note that AD Pro 3250 is supposed to have 64 MiSamples for playback, so I'm not expecting to run into memory issues.
