[USRP-users] ADC self-test failed

Hi Nate,

Sure, our company is using a custom UHD and I will have to redact part of
the text. When I run the command it outputs:
003.009.001*<this-is-redacted>*
This x300 has always been problematic. We have a different X300 that works
fine with this setup. The problem occurs when I duplicate the setup for use
with our second X300. We need the second setup running also. I have never
updated the UHD.
Hopefully this is helpful, I assume our custom UHD is built from
003.009.001.

Thanks so much,
Sam
