33. Spurious Response, HP 8596EM
4.Adjust the synthesized sweeper power level to place the peak of the signal displayed on the EMC analyzer at the reference level (77 dBV).
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 dBV.
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 verication test record. The amplitude reading should be less than the specied limit.
Note that the maximum MKR 1 Amplitude Reading is 20 dB higher than the specication. This is a result of changing the reference level from 77 dBV to 57 dBV.
Part 2: Second Harmonic Distortion, >2.9 GHz
10.Zero and calibrate the measuring receiver and 50 MHz to 12.8 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.
11.Measure the noise level at 5.6 GHz using the following steps:
a. Remove any cable or adapters from the EMC analyzer INPUT 50 .
