Hello!

I have an USRP with two daughterboards (RFX1800) using an external
clock (with 64 MHz).

Running
# usrp_siggen.py -T A -f 1819.4e6

shows me the spectrums:
http://ud05_188.ud05.udmedia.de/gnuradio/nah.PNG
http://ud05_188.ud05.udmedia.de/gnuradio/gesamt.PNG

There are several peaks near center frequency 1819.4 MHz and some
others (offset ~190-320 MHz). Does the spectrum look good?
I ask, because I'm not sure if the spectrum has changed since using an
external clock.

Thanks & Regards

Yes, that spectrum looks correct.
