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 the input of the AM Detector being used. The AM
sideband (spur) level relative to the carrier level (dBc) and the spur offset
frequency must be determined using an RF spectrum analyzer. You will
be required to define the relative level and offset frequency values in the
Calibration Process display either during the measurement definition or
when you reach the Connect Diagram.
The system measures the spur level at the output of the detector and
calculates the Detector Constant.
Calibr Process: AM Noise 2-97
