[Discuss-gnuradio] Questions on the usrp_fft and usrp_oscope

[Sachi]

Hi, guys

I met some confusions when I tried the usrp_fft and
usrp_oscope.

I generate a 2MHz, peak to peak 1V, sin wave using the
Agilent signal generator, and connect it to usrp.
However, the result of usrp_fft always shows a very
strong component at DC, besides the 2MHz. Why is that?


Then I tried usrp_oscope, it works pretty well. But
when I zoom in, I found the wave form doesn't seem to
be sine, but something like square or triangle. Do I
miss any parameters here?

Thanks so much
Sachi
