Subject: Pi attenuator on eval board inputs? 

The attenuator compensates for the gain of the buffer which is slightly above one. In addition, it serves as a "placeholder" in case one wants larger input signals. One can easily convert the attenuator to -6db, -12db, etc. by chaning the resistors.

Dear DRS4 team,

 

I am curious about this part of the circuit:

What is the purpose of this?
