38. Gain Compression, HP 8596EM

23.On synthesized sweeper #2, adjust the power level to place the signal 1 dB below the EMC analyzer reference level.

24.On the EMC analyzer, press 4MKR !5 MKR ! HIGH More 1 of 3

More 2 of 3 MARKER 1 .

25.On synthesized sweeper #1, set RF to ON.

26.On the EMC analyzer, press 4MKR !5 MKR ! HIGH , then NEXT PEAK .

The active marker should be on the lower amplitude signal and not on the signal that is o￿ the top of the screen. If it is not on the lower amplitude signal, reposition the marker to this peak using the EMC analyzer knob.

27.Read the MKR 1 amplitude and record in the performance veri￿cation test record as TR Entry 2. The absolute value of this amplitude should be less than or equal to 0.5 dB.

Narrow Bandwidth

28.Remove the EMC analyzer from the directional coupler and reconnect the measuring receiver power sensor to the directional coupler as shown in Figure 2-60.

29.Press INSTRUMENT PRESET on both synthesized sweepers.

30.Set synthesized sweeper #1 controls as follows:

CW : : : : : : :: :: : : : : : : :: : : : :: : : :: : : : : : : : : : : : : :: : : : : : : : : : : : :: :: : : : : : : 50.010 MHz

POWER LEVEL : :: :: :: :: : : : : : : : : : : : : : : : : : : : :: :: :: : : : : : : : : : :: : : : :: : : : : : 0 dBm

31. Set synthesized sweeper #2 controls as follows:

CW :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: 50 MHz

POWER LEVEL : :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: 014 dBm

RF :: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: OFF

32.On synthesized sweeper #1, adjust the power level for a 0 dBm reading on the measuring receiver. Set RF to OFF.

33.On synthesized sweeper #2, set the RF to ON.

34.Disconnect the power sensor from the directional coupler and connect the directional coupler to the INPUT 50 ￿ connector of the EMC analyzer using an adapter. Do not use a cable.
