30. Spurious Response, HP 8593EM
45.If the distortion products can be seen, proceed as follows:
a.On the EMC analyzer, press 4MKR !5, MARKER ! HIGH , More 1 of 3 ,
More 2 of 3 , and MARKER 1 .
b.Press More 3 of 3 then repeatedly press NEXT PEAK until the active marker is on the highest distortion product.
c.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.
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:
