7. With the frequency function active, adjust the INCR SET to 100 Hz.
Press the
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:
9. Press
10.Set the synthesized signal generator to the level recorded in
and adjust A14R23 SLOPE (refer to
of 1000 mV ±1 mV.
From this point on, the power level will be controlled by the 8496G
10 dB step attenuator.
