Hm, I don't understand what you are attempting to measure. Measuring the
input IP3 (IIP3) for a transmitter doesn't mean anything. All that matters
is output IP3 (OIP3). The e-mail you linked to is Marcus explaining how to
measure the IIP3 through the receive-only port of a daughterboard
Let me preface this by saying I mostly lurk on this list, and haven't
touched a USRP of any variety, so I'm unfamiliar with their gain lineup.
However, looking at this data, a couple of things come to mind.
1-You're sweeping the gain by 35 dB, and the amplitude is moving by 28 dB,
which seems to i
Apologies that copy paste formatting was attrocious..! Data attached in
file.
P.S. earlier I meant to say f1 = 4MHz and f2 = 5 MHz
In the attached data
m1 = 2*f1-f2
m2 = f1
m3 = f2
m4 = 2*f2-f1
thx!
