Power Detector Adjustment

The power detector requires correction data to allow conversion of the raw detector reading to power in dBm. The Link Subsystem (LSS) is used as a CW source at a known power output at one frequency. The signal is routed to the power detector and its voltage is read. The signal is routed through the RF assembly and measured using calibrated external test equipment. The output from the N4010A is measured by a spectrum analyzer. Traceability for the spectrum analyzer measurements is achieved through cross calibration with a power meter.
