14. A djust the display line so that it is centered on the average trace noise ,
ignoring any residual responses . Record the display line amplitude setting in
T able 2-77 as the noise level at 400 kHz.
15. Repeat steps 13 and 14 for the remaining Tracking Generator Output
Frequencies (EMC analyzer center frequency) listed in T able 2-77 .
16. In T able 2-77, locate the most positive Noise Level Amplitude from 400
kHz to 5 MHz. Record this amplitude as TR Entry 1 of the performance
verication test record.
17. In T able 2-77, locate the most positive Noise Level Amplitude from 5 MHz
to 2900 MHz. Record this amplitude as TR Entry 2 of the performance
verication test record.
