How to connect the EV2HMC7585LG (Tx) with EV2HMC8327LG (Tx)

Hi, 

I am testing the mm-wave a transmitter (EV2HMC7585LG) and a receiver (EV2HMC8327LG). They are directly connected with a 30dB attenuator.

However, I can see nothing from the IF outputs, even applying FFT for the received signals. Are my connections correct?

Also, there are many jumper connections on the boards. One is disconnected by default. I do not know exactly what are those jumpers used for. Is there any user guide I can refer?

Thank you,

Weite Zhang
