I am using an ADC of FMC150 on ML605. The ADCs on FMC150 are AC coupled. There are capacitors in front of these ADCs. I input multiple waveform e.g. 100-kHz square pulses to one of the ADCs. The waveform that were sampled by the ADC was distorted. I think this is due to the frequency characteristics of the capacitors in front of the ADC. Can anybody give me any advice to remove this AC coupling effect?

Not as I am aware of. The most obvious solution is to use a DC coupled card, the FMC151 is the DC coupled version of the FMC150.
