I confused as to how the USRP FPGA scales the ADC signal. It appears
that on the setup we are using, which has some customized DC Rx
daughter boards, when we put in a 2V p-p square wave with a DDC center
frequency of zero and a decimation rate of 64 we are getting data that
is p-p ~16000 counts, is this normal? I'll be checking how the normal
Rx boards behave on Sunday.
Krys,
Seems low, but it may be normal. Matt could confirm, but he's on his
way to Green Bank.

I measured the signal with the normal RX daughter boards and I got the same results. A 2V p-p sine
signal (measured simultaniously on a real oscilloscope) showed a ~16000 count p-p signal in the
gnuradio oscilloscope display.
