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. www.pellegrini-radio.it/uhd_003.004.000-f500b92.jpg www.pellegrini-radio.it/uhd_003.005.002.jpg 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 -- Vincenzo Pellegrini http://www.youtube.com/user/wwvince1
