3.Press INSTRUMENT PRESET on the synthesized sweeper. Set the synthesized sweeper controls as follows:
POWER LEVEL : :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: ::: 06 dBm
CW : ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: : 50 MHz
RF : :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: ::: :: : OFF
4. Set the synthesizer/level generator controls as follows:
FREQUENCY :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: :: : 50.050 MHz
AMPLITUDE :: :: :: :: ::: :: :: :: ::: :: :: :: :: ::: :: :: :: ::: :: :: :: : 06 dBm
50/75 SWITCH :: :: :: ::: :: :: :: ::: :: :: :: :: ::: 75 (no RF output)
5.On the EMC analyzer, press 4PRESET5, then wait until the preset routine is nished. Set the EMC analyzer by pressing the following keys:
4FREQUENCY5 50 4MHz5
4SPAN5 10 4MHz5
4AMPLITUDE5 97 4+dBV5
4MKR !5 MARKER ! HIGH More 1 of 3 PEAK EXCURSN 3 4 dB 5 4DISPLAY5 More 1 of 2 THRESHLD ON OFF (ON) 17 dBV
6.On the synthesized sweeper, set RF on. Adjust the power level until the measuring receiver reads 012 dBm 60.05 dB.
7.Disconnect the 100 kHz to 4.2 GHZ power sensor from the directional bridge. Connect the directional bridge directly to the EMC analyzer RF INPUT using an adapter (do not use a cable).
8.On the EMC analyzer, press the following keys:
4MKR !5 MARKER ! HIGH
4MKR5 More 1 of 3 MK TRACK ON OFF (ON)
4SPAN5 200 4kHz5
Wait for the AUTO ZOOM message to disappear, then press the following EMC analyzer keys:
4MKR5 More 1 of 3 MK TRACK ON OFF (OFF)
4MKR !5 MARKER ! HIGH More 1 of 3 MARKER !REF LVL
9.On the synthesized level generator, set the 50 /75 switch to the 50 position (RF on). Adjust the amplitude until the two signals are displayed at the same amplitude.
