Recommended input voltage for AD9234 (AD9680) Evaluation board

Hi,

I am using an AD9234 Evaluation board (This Version:

AD9234-1000EBZ Evaluation board for AD9234-1000; Full Bandwidth 9680CE04B

)

For testing I  would like to know what kind of input signal I should sent to the Evaluation board input CH A, as I can not found information from here https://wiki.analog.com/resources/eval/ad9680-1000ebz

Thanks,

Nils
