bladeRF 2.0 xA4 Reference Clock setup

Hello,

I am working on setting up my bladeRF with a GPSDO 10MHz reference clock. https://github.com/Maxwell175/EmailSMS/ ... 55b845.pdf

After connecting it through a 10dB attenuator to Ref IN and running "set clock_ref enable" in the cli it seems like the stability of my srsLTE setup might have only gotten worse. Is my setup correct?

That is what I did as I showed in the photo above. Is there anything wrong with the cable I am using? It is directly BNC on one end and U.FL on the other end with no splices.

This unfortunately won't help with the original question, but how many posts come from bots nowadays on this forum? All answers above seem like they may come from bots, just giving general info more or less linked to the question...

did you ever figure it out? I might need an external clock so i am assuming i will need to purchase a U.FL connector.

Your setup with the bladeRF and GPSDO 10 MHz reference clock might require some fine-tuning. Start by verifying the GPSDO signal quality and reconsidering the need for a 10dB attenuator.
