7. With the frequency function active, adjust the INCR SET to 100 Hz.
Press the
⇑ (step-up key) to maximize the signal level on screen.
Adjust the synthesized signal generator amplitude as necessary to
keep the signal on the display.
8. Adjust the synthesized signal generator output level for a DMM
reading of 1000 mV ±7.0 mV. Record the synthesized sweeper
amplitude readout for later reference:
____________________dBm
9. Press
SCALE (LOG) on the analyzer.
10.Set the synthesized signal generator to the level recorded in step 8
and adjust A14R23 SLOPE (refer to Figure 2a-3) for a DMM reading
of 1000 mV ±1mV.
From this point on, the power level will be controlled by the 8496G
10 dB step attenuator.
