Derive From Single Sided Spur
Introduction
The Derive From Single Sided Spur method is a very accurate method
for calibrating the Detector Constant. However, it requires additional
equipment and presents a high level of technical difficulty.
This calibration method requires that an additional signal (representing the
spur) is applied to one of the phase detector inputs. The sideband (spur)
level relative to the carrier level (dBc) and the spur offset frequency must
first be determined using an RF spectrum analyzer. You will be required
to enter the relative level and offset frequency values in the Calibration
Process display either during measurement definition or when you reach
the Connect Diagram.
The system measures the phase detector output for the known spur levels
and calculates the Phase Detector Constant.
