Re: [Discuss-gnuradio] B200 clock calibration

[Nick Foster]

The ADF4001's output charge pump is tristated when not locking to an external reference, and a resistor divider holds the VCTCXO's tuning input at 1/2 Vcc. The B200 hardware can use the AD9361's low-speed DAC to drive the VCTCXO's tuning input via AUXDAC1 if R118 is populated; however, this functionality is not supported by the B200 UHD driver.

Hi, In case we use on-board oscillator , how is ADF4001 configured? Does CP (pin20) output affect the VCXO_Tune ? Is it possible to control this chip directly from the command line?
