The problem has now been solved. I had assumed the USRP2's
DAC sample rate of 400 MS/s was the rate I had to interpolate to.
Not so, it should be 100/s MS/s.
Thanks all

You should definitely be able to see something at 1.001GHz, but any
residual DC offset will also cause a spike at 1.000GHz when using a
vector modulator.

Hello,
I have been playing around with the USRP2, mainly to
get a feeling for how much data I can pass across the
Ethernet.
I have noticed something odd
When I use sig_source_c with a sample rate of 20 Ms/s
and a frequency of 1 MHz with the WBX board set to
1 GHz and the interpolation set t
