Introduction
The calibration process for a phase lock loop measurement involves
determining the Phase Detector Constant, the VCO Tuning Constant,
and verifying the Loop Suppression. The Phase Detector Constant is the
sensitivity of the phase detector expressed in volts per radian (V/Rad). The
VCO Tuning Constant is the sensitivity of the tuning input of the Voltage
Controlled Oscillator (VCO) expressed in Hertz per volt (Hz/V). The Loop
Suppression verification characterizes the phase lock loop configured for
the measurement and then compares the measured loop response with a
theoretical loop suppression curve.
