Hi all, We are measuring the output power of the N310 when streaming a CW signal (with the example tx_waveforms), with different values of "gain". The exact command we use is:
./tx_waveforms --args=addr=192.168.20.2,master_clock_rate=153.6e6 --rate=25600000 --freq=1575420000 --ref=external --pps=external --channels=0 --ampl=0.296 --gain=XXX We are under Ubuntu 18.04, and using UHD 3.13.1.0 The output power is pretty linear for gain values between 0 and 52, which is expected. However, there is a +3dB jump between gain values of 34 and 35, instead of +1dB. (So, between 0 and 52, there is actually 54dB difference instead of 52) Q: Is this "expected", or can this be explained? Q: Will this "jump" be present for all revision of N310 devices, or UHD versions? Thanks! Serge
