ctrum for the TwinRx (for example for UBX the spectrum noisefloor is much more flat). For this reason, I am asking if someone can provide a plot of the spectrum of both channels at a sampling rate of 100 Msps. Thank you. Regards, Carlo Venier Il gio 22 giu 2023, 15:30 Marcus D. Leech ha scritto:

[USRP-users] TwinRx in coherent setup

le until a power-cycle. I get the same issues when using both the uhd3.15.0.0 and the uhd4.4.0.0. Should I expect the same phase differences when I re-tune to the exact same frequency or is it okay for the phase differences to change and I am missing something? Do yo

Thank you for the screenshot, Marcus. The noise floor shape you obtain has the same behaviour as the noise floor shape we obtain. So, assuming this is the "nominal" behaviour, do you have any equalization method to suggest? Regards, Carlo Venier Il mer 28 giu 2023, 20:02 Marcus D.

[USRP-users] Questions regarding tx_waveforms

2020-12-02 Thread Carlo Venier via USRP-users
Hi, I have a few questions regarding tx_waveforms script. I'm using an USRP B200mini. How can I delete (or reduce) the DC component when using tx_waveform? When I set --freq=f0, specifying --lo_offset=(df0), how do I remove (or reduce) the mirrored replica at (f0+2*f0) that is generated? Do you
