Hi Mubeen, Glad you were able to get things to work. If increasing the S+H helped, probably the issue was with the input network. The ControlCard has footprints for capacitors on the ADC inputs. As you further refine your prototype, you might want to populate these at some point. Locally buffering the signal with a low-noise and high bandwidth op-amp is also immensely helpful for getting good signal integrity at high sample rates.
