How to connect XM500 to zcu111

I have the zcu111 board and xm500, i use 4 ADCs and 4 DACs.  In 1217, it said

• Two DACs and two ADCs routed to HF baluns with –1dB Pi pad attenuators and then to SMAs

• Two DACs and two ADCs routed to LF baluns with –3dB Pi pad attenuators and then to SMAs

• Four DACs and four ADCs routed to SMAs for use with external custom baluns and filters.

In my use, i need 2GHz bandwidth. so my questions are:

1) if i use "Two DACs and two ADCs routed to HF baluns....", i can connect the SMAs of ADCs to signal generator directly, right?  Does it need to connect to filters? I saw some filters in the evaluation kit I bought. I do not know what they are for.

2) What is the power range of the signal input to ADC? What is the power range of the signal output from ADC? Here i mean the SAM interface on the XM500.

3)If I use"Four DACs and four ADCs routed to SMAs for use with external custom baluns and filters", that means, I still need some other baluns and filters besides the XM500 board, right? But how can i konw  the parameters for the baluns and filters?

Thanks.
