Hi, I assume you are using internal clock? 5kHz is within its spec (barely). My units vary in that range, although not as much individually. Kind regards, John

After some time, we wanted to build this setup again but we ran into an issue: The phone never found the cell. After looking into the problem I noticed, that the output frequency of the B200 is shifted around +5 kHz at around 2.6 GHz (Verified it with another SDR). Too much for the phone to get the signal properly. When I manually adjust the frequency in srsRAN to compensate for the 5 kHz shift, the phone immediately detects the cell. At lower frequencies, the shift also gets lower. Is there something we can do to revive the B200? Because this exact setup worked in the past, I think something happened to the b200 that causes this shift.
