bladeRF 2.0 xA4 - trimdac

[anvol]

Hi,

I've noticed that onboard vctcxo gives 38.46 MHz instead of strict 38.4
So I've decided to trim it manually, using clock out and oscilloscope setup.

But after tinkering with "set trimdac 0x1ed7" (factory calibrated value) +/- some small and then bigger values I see no difference on the oscilloscope.

print hardware tells me that current dac value has been changed. But clock out stays the same — 38.46 MHz.

What's the right procedure for manual calibration?

Thanks in advance

I'm also looking for some information on this.
