setting clock_ref in gr-bladeRF
Posted: Fri May 20, 2022 5:03 pm
Hi,
I'm using a bladerf 2.0 A9 unit. I've installed the gr-bladeRF source block, and I have it working. I've experimented with providing a 10 MHz external reference through the J95 connector. I notice that the gnuradio source block has an entry to specify the reference frequency, but nowhere to enable the ADF4002. The bladeRF-cli program has "set clock_ref enable", but not the source block. But I notice that when I turn on my external 10 MHz reference (a Bliley OCXO) the spectrum of a continuous tone really cleans up, losing its big phase noise sidebands. So is the blade automatically sensing the external reference? Or is there a need to include the clock_ref in the source block.
Thanks much!
