[USRP-users] N32x - Signal amplitude distorted when NOT using coherent frontend ?

2022-03-16 Thread tebetix672--- via USRP-users
Hello! I have been doing a simple test where an impulse (with a rather small duty cycle) is sent over a (short) wire and then captured by two N32x boards synchronized with White Rabbit. The B210 has a sampling rate of 4 Msps, while I’ve tried using both 10 Msps and 5 Msps for the N32x (with the

Could this be an issue related to automatic DC bias calibration? If you are using a "DC" pulse (that is, at 0 Hz relative to the LO), perhaps you are seeing effects from DC bias cancellation. You can either turn off this calibration using the appropriate "args" at startup or you could request an L

Hello Rob, Thanks for your reply! Actually I was observing the same phenomenon, though significantly less pronounced, with a sine wave. In the dsp-related forum they’ve pointed me to the fact that it could be due to the sampling phase (emitter and receivers do not share the LOs), I still have t

[USRP-users] LP0965 Antenna

Dear community, I have purchased a few LP0965 Antennas (https://www.ettus.com/all-products/lp0965/) because I would like to do a 5G transmission at 3.5 GHz (using OpenAirInterface). Is there any guidelines that I can follow for deployment? For example, in the link it mentions that "The SMA c
