17. Resolution (IF) Bandwidth A ccuracy , HP 8590 EM-Series
A djust the synthesizer/level generator amplitude to place the peak of the
signal at or below the top graticule .
7. On the synthesizer/level generator , press AMPLITUDE and INCR 4 + 5
(step-down key).

NNNNNNNNNNNNNNNNNNNNNNNNNN
MARKER 1 on the EMC analyzer .
9. On the synthesizer/level generator , press INCR 4 * 5 (step-up key).
10. 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.
11. Record the synthesizer/level generator frequency readout in column 1 of
T able 2-21 .
12. Using the synthesizer/level generator knob , raise the frequency so that the
marker-delta amplitude is maximum. Continue increasing the frequency
until the marker reads 0.0 6 0.05 dB.
13. Record the synthesizer/level generator frequency readout in column 2 of
T able 2-21 .
14. A djust the synthesizer/level generator frequency for maximum amplitude .
15. Repeat steps 5 through 14 for each of the RES BW settings listed in
T able 2-21 .
16. Subtract the Synthesizer Lower Frequency from the Synthesizer Upper
Frequency . Record the dierence as the Resolution Bandwidth A ccuracy , in
the performance verication test record as indicated in T able 2-21 .
