This performance verication 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 RA TIO 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 dierence relative to the power level at 300 MHz is
measured at each frequency and recorded.
The related adjustment for this procedure is \Modulator Oset and Gain for
Option 010, HP 8591EM."
