Hi everybody,
I have been experiencing some difficulties in obtaining
the same "signal clarity" performance that I used to have with
uhd_003.004.000-f500b92
when I tried to transmit the same samples of the same signal
(also same usrp B100, same XCVR2450 front-end, same frequency =5.8GHz, same receiving device, same tx/rx antenna positions)
with both:
uhd_003.005.001
and
uhd_003.005.002
at the following links you can find images of a DVB-T modulation analyzer exposed to both transmissions.
If you look at the MER value, a much poorer constellation quality is evident when operating with the newer UHD and its matched images.
(no performance difference was noticed in this respect between uhd_003.005.001 and uhd_003.005.002).
Has this been experienced before?
As somethin changed in between that I should be aware of?
my best regards to everybody
vince
