35. Gain Compression, HP 8593EM
17. Set synthesized sweeper #1 controls as follows:
CW : ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: 4.003 GHz
POWER LEVEL : :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: : 2 dBm
18. Set synthesized sweeper #2 controls as follows:
CW :: :: ::: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: : 4.0 GHz
POWER LEVEL : :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: 014 dBm
19.Enter the power sensor CAL Factor into the measuring receiver.
20.On synthesized sweeper #1, adjust the power level for a 0 dBm reading on the measuring receiver. Set RF to o.
21.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.
22.On the EMC analyzer, press the following keys:
4MKR !5 MKR ! HIGH
4MKR5 More 1 of 3 MK TRACK ON OFF (ON)
Wait for the signal to be centered on screen.
4AMPLITUDE5 More 1 of 3 PRESEL PEAK
Wait for the CAL: PEAKING message to disappear.
4SPAN5 10 4MHz5
Wait for the AUTO ZOOM message to disappear.
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.
