Yes, LO leakage, more specifically DC imbalance in the I and Q channels; I
assume you are using a daughter board with an IQ modulator? This is
supposedly corrected for in the firmware, however, probably not done over
temperature. You can probably tweak it by adding/subtracting a few LSB of
DC of

Hello:
I have a USRP2 board and a WBX daughterboard. I am trying to implement a scheme
where a single-tone sine wave (at frequencies between 1 kHz and 10 kHz) is
transmitted intermittently. Specifically, time is divided into intervals,
defined by the user on the command line, typically of value
