[casper] wideband spectrometer

[f.schilliro]

Hi everybody, it's Fancesco from Italian INAF, Radiotelescope of Noto.
I'm a beginner using ROACH, I've mounted wideband spectrometer tut 3 on
my roach (r_spec_2048_r105_2010_Jul_26_1205.bof)  and I think the
connections to IF, clock (800 MHz with O  dBm) and sync should be 
right, because I'm able to
monitor the IF samples (with adcmon); the problem is that final 
spectrum is totally
composed by zero samples. Could you help me?

thanks,
Francesco
