This performance verication test must be performed with the EMC analyzer set in the spectrum analyzer mode.
The output of the synthesized sweeper is fed through a power splitter to a power sensor and the EMC analyzer. The synthesized sweeper's power level is adjusted at 300 MHz to place the displayed signal at the EMC analyzer center horizontal graticule line. The measuring receiver, used as a power meter, is placed in RATIO mode. At each new sweeper frequency and EMC analyzer center frequency setting, the sweeper's power level is adjusted to place the signal at the center horizontal graticule line. The measuring receiver displays the inverse of the frequency response relative to 300 MHz (CAL OUT frequency).
