32. Spurious Response, HP 8595EM
46.If the distortion products cannot be seen, proceed as follows:
a.On both the synthesized sweeper and the synthesized level generator, increase the POWER LEVEL by 5 dB. Distortion products should now be visible at this higher power level.
b.On the EMC analyzer, press 4MKR !5, MARKER ! HIGH , More 1 of 3 ,
More 2 of 3 , and MARKER 1 .
c.Press More 3 of 3 then repeatedly press NEXT PEAK until the active marker is on the highest distortion products.
d.On both the synthesized sweeper and the synthesizer level generator, reduce the power level by 5 dB and wait for the completion of a new sweep.
e.Record the MKR 1 amplitude reading as TR Entry 2 of the performance verication test record. The MKR 1 reading should be less than 054 dBc.
Part 4: Third Order Intermodulation Distortion, >2.9 GHz
47.Enter the Power Sensor 4 GHz Cal Factor into the measuring receiver.
48.Disconnect the directional coupler from the EMC analyzer, then connect the power sensor to the output of the directional coupler.
49.Set each of the synthesized sweeper controls as follows:
POWER LEVEL :: : : : :: :: : : : : : :: : : :: : : : :: : : : : : :: :: : : : : : : : : : 015 dBm
CW (synthesized sweeper #1) :: : : :: : : : :: :: :: :: : :: : : : : : : : :4.000 GHz
CW (synthesized sweeper #2) : : : : : : : :: :: : : : : : : : : : : :: : : 4.00005 GHz
RF : : : : : : : : : : : : : : : : : : : : : : : : : : :: : : : :: : : :: :: :: :: : : : : : : : :: : : : : : : : :: : OFF
50.On the EMC analyzer, press 4PRESET5, then wait until the preset routine is nished. Set the EMC analyzer by pressing the following keys:
4FREQUENCY5 4.0 4GHz5
4SPAN5 1 4MHz5
4BW5 REF LVL 97 4+dBV5
4MKR !5 MARKER ! HIGH More 1 of 3 PEAK EXCURSN 3 4dB5 4DISPLAY5 THRESHLD ON OFF 17 4+dBV5
51.On synthesized sweeper #1, set RF on. Adjust the power level until the measuring receiver reads 012 dBm 60.05 dB.
