62. CISPR Pulse Response, HP 8590 EM-Series

CW Measurement for 9 kHz EMI Bandwidth

50.Press 4PRESET5 on the EMC analyzer. Wait for the preset routine to ￿nish.

51.Press 4RECALL5 1 on the pulse generator.

52.Press 4RECALL5 2 on the synthesizer/level generator.

53.Press the following keys on the EMC analyzer:

4SAVE/RECALL5 Recall Internal INTERNAL ! STATE 1

4MKR5 MARKER NORMAL

4SPAN5 20 4kHz5

4BW5 9 kHz EMI BW

4DET5 QP ON OFF (ON)

Note that this routine takes approximately 1 minute to execute.

4AMPLITUDE5 REF LVL 67 dB￿V

4MKR !5 MARKER ! HIGH

54.Record the quasi-peak reading displayed below the signal on the EMC analyzer screen in Table 2-81, under the Measured CW Amplitude for 9 kHz.
