1. Connect equipment as shown in Figure 2-31 with the synthesized
sweeper RF OUTPUT connected to the analyzer input.

6. Adjust the power level of the synthesized sweeper to place the
peak of the signal trace at the top CRT graticule line.
If the maximum output power level of the synthesized sweeper is not
enough to place the signal peak at the top CRT graticule line, then
adjust the spectrum analyzer REFERENCE LEVEL as.required to
place the signal peak at the top CRT graticule line.
7. Press MARKER Ia]. Using the DATA knob, determine the
amplitude of the spurious response and enter the result in
8. Set the synthesized sweeper to the frequencies in 'Pable 2-20
corresponding to an analyzer center frequency of 3 GHz. The
maximum allowable amplitude of the spurious response at the
analyzer center frequency for each setting is shown in the table.
