3. Press Peak Search. Record the marker frequency next to your analyzer model in the
Measured Frequency column as entry (s) or (t) in Table 4-1 on page138 for 22.01 GHz to
26.5 GHz.

5. Press Center Freq. Set the center frequency of the analyzer to the frequency recorded in
the Measured Frequency column as entry (s) or (t) in Table 4-1 on page 138 for 22.01
GHz to 26.5 GHz.
6. Press the following keys on the analyzer:
BW/Avg, Res BW, 1, kHz
Video BW, 30, Hz

Wait for the sweep to finish.
7. Press the following keys on the analyzer:
Display, Display Line (On)
Adjust the display line so that it is centered on the average trace noise, ignoring any
residual responses.
8. Record the display line amplitude setting as TR Entry 17 or 18 in Table4-1 on page 138.
The Average Noise Level should be less than the Maximum.
