52.Tracking Generator Level Flatness ,

HP 8591EM Option 010

This performance veri￿cation test must be performed with the EMC analyzer set in the spectrum analyzer mode.

The tracking generator output is connected to the EMC analyzer input and the tracking is adjusted at 300 MHz for a maximum signal level. A calibrated power sensor is then connected to the tracking generator output to measure the power level at 300 MHz. The measuring receiver is set for RATIO mode so that future power level readings are in dB relative to the power level at 300 MHz.

The tracking generator is then stepped to several frequencies throughout its range. The output power di￿erence relative to the power level at 300 MHz is measured at each frequency and recorded.

The related adjustment for this procedure is \Modulator O￿set and Gain for Option 010, HP 8591EM."
