6 dB EMI Bandwidths

17.Set the synthesizer/level generator AMPTD INCR to 6 dB.

18.On the EMC analyzer, press the following keys:

4BW5 9 kHz EMI BW

4MKR5 MARKER NORMAL

19.On the synthesizer/level generator, press FREQUENCY. Adjust the frequency for a maximum marker reading.

20.On the synthesizer/level generator, press AMPLITUDE and INCR 4+5 (step-down key).

21.Press MARKER 1 on the EMC analyzer.

22.On the synthesizer/level generator, press INCR 4*5 (step-up key).

23.On the synthesizer/level generator, press FREQUENCY. Lower the frequency of the synthesizer/level generator by adjusting the knob until the marker-delta amplitude is 0.0 6 0.05 dB.

24.Record the synthesizer/level generator frequency readout in column 1 of Table 2-22.
