This performance verication test must be performed with the EMC analyzer set
in the spectrum analyzer mode.
The RF INPUT coupling is rst set to the dc coupled 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 analyzer center horizontal graticule line . The
measuring receiver , used as a power meter , is placed in RA TIO mode . At each
new sweeper frequency and 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).
