Signal Decay with USRP N210 Using BasicRX

So I’ve been doing some development and my USRP using a custom RF front
via the BasicRX daughter board and have noticed an RC decay. I thought
was my system, but I recently just put a signal generator directly into
USRP and noticed the same thing (although not as high of a time
My high frequencies are passing through fine (sharp transitions are
present), but when a level is held at a positive or negative voltage, it
decays to zero.

Is there a limitation on the USRP or BasicRX card? Or something else I’m

Yes, the basic boards cannot pass DC (and low frequency). You will want
an LFRX for that. -josh
