35. Gain Compression, HP 8593EM
Option 026 only: Connect the directional coupler to the EMC analyzer directly.
9. On the EMC analyzer, press the following keys:
4MKR !5 MKR ! HIGH
4MKR5 More 1 of 3 MK TRACK ON OFF (ON)
4SPAN5 10 4MHz5
Wait for the AUTO ZOOM routine to nish.
10.On synthesized sweeper #2, adjust the power level to place the signal 1 dB below the EMC analyzer reference level.
11.On the EMC analyzer, press 4MKR !5 MKR ! HIGH More 1 of 3
More 2 of 3 MARKER 1 .
12.On synthesized sweeper #1, set RF to ON.
13.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.
14.Read the MKR 1 amplitude and record in the performance verication test record as TR Entry 1. The absolute value of this amplitude should be less than 0.5 dB.
Gain Compression, >2.9 GHz
15.Disconnect the directional coupler from the EMC analyzer input, then connect the directional coupler to the power sensor.
16.Set the EMC analyzer by pressing the following key:
4FREQUENCY5 4.0 4GHz5
4SPAN5 20 4MHz5
4MKR5 More 1 of 3 MARKER ALL OFF
