ADCMP600 Eval Board

Hello,

I am having trouble seeing the expected signals from my ADCMP600 Eval Board. When connected to 50ohm terminated scope, the output voltage is less than 1/2 of what I expect. If connected to a 1M termination, I can see more of the output swing however there are some really bad reflections and I cannot measure appropriate timing signals.

Is the part not capable of driving 50 ohms? Is there a users guide to help guide through the use of the board?

Regards,

Jonathan
