30. Spurious Response, HP 8593EM

3.Press 4PRESET5 on the EMC analyzer, then wait for the preset routine to ￿nish. Set the EMC analyzer by pressing the following keys:

4FREQUENCY5 30 4MHz5

4SPAN5 1 4MHz5

4AMPLITUDE5 REF LVL 77 dB￿V

4BW5 IF BW AUTO MAN (MAN) 30 4kHz5

4.Adjust the synthesized sweeper power level to place the peak of the signal displayed on the EMC analyzer at the reference level of 77 dB￿V.

5.Press the following EMC analyzer keys:

4BW5 IF BW AUTO MAN (MAN) 1 4kHz5

AVG BW AUTO MAN (MAN) 100 4Hz5

6. Wait for two sweeps to ￿nish, then press the following EMC analyzer keys:

4MKR !5 MARKER ! HIGH

More 1 of 3 MKR ! CF STEP

4MKR5 MARKER 1

4FREQUENCY5

7.Press the 4*5 (step up) key on the EMC analyzer to step to the second harmonic (at 60 MHz). Set the reference level to 57 dB￿V.

8.Wait for one full sweep, then press 4MKR !5 MARKER ! HIGH .

9.Record the MKR 1 Amplitude reading as TR Entry 1 of the performance veri￿cation test record. The amplitude reading should be less than the speci￿ed limit.

Note that the maximum MKR 1 Amplitude Reading is 20 dB higher than the speci￿cation. This is a result of changing the reference level from 77 dB￿V to 57 dB￿V.

Part 2: Second Harmonic Distortion, >2.9 GHz

10.Zero and calibrate the measuring receiver and 50 MHz to 26.5 GHz power sensor in log mode (power reads out in dBm), as described in the measuring receiver operation manual. Enter the power sensor 3 GHz Cal Factor into the measuring receiver.
