Hi Stefan,

    when I sample a constant input with the DRS 4 chip, there was a baseline variation showing up as a saw-tooth pattern which grows with the absolute value of the differential input. Do you think this is the kind of baseline variation mentioned in the evaluation board manual, i.e. coming from clock jitter in ADC sampling?

    Thanks a lot!

 

Please post an oscilloscope screenshot here and I can tell you.
