29. Spurious Response, HP 8591EM

12.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 veri￿cation test record. The MKR 1 reading should be less than 054 dBc.

13.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 veri￿cation test record. The MKR 1 reading should be less than 054 dBc.
