11.On the analyzer, press: FREQUENCY, ↑.
12.If the resolution bandwidth is ≥1 kHz, press: SPAN, 4 kHz.
13.On the synthesized sweeper, set the RF on.
14.On the analyzer, press Peak Search (or Search).
15.On the synthesized sweeper, adjust the power level until the marker
delta (∆ Mkr1) amplitude reads 0 dB ±0.05 dB.
16.On the analyzer, press FREQUENCY, ↓, ↓. The center frequency
should now be lower than the signal generator frequency by the CF
Step value.
17.Set the analyzer reference level to –15 dBm.
18.On the analyzer, press: BW/Avg, Average, 20, and wait for “Vavg 20”
to appear along the left side of the display.
19.On the analyzer, press Peak Search (or Search) and record the marker
amplitude reading in Table 2-72 as the Lower Distortion Amplitude.
20.On the analyzer, press: BW/Avg, Average Off.
21.On the analyzer, press FREQUENCY, Center Freq, ↑, ↑, ↑. The center
frequency should now be one CF Step value above the synthesized
sweeper frequency.
22.Set the synthesized signal generator frequency to F2 as indicated in
Table 2-71.
23.Set the synthesized sweep CW frequency to F1 as indicated in
Table 2-71.
24.On the analyzer, press BW/Avg, Average, 20, and wait for “Vavg 20”
to appear along the left side of the display.
25.On the analyzer, press Peak Search (or Search) and record the marker
amplitude reading in Table 2-72 as the Upper Distortion Amplitude.
26.On the analyzer, press BW/Avg, Average Off.
27.Of the Lower Distortion Amplitude and Upper Distortion
Amplitudes recorded in Table 2-72, enter the most positive value as
the Worst Distortion Amplitude in Table 2-72. For example, if the
Upper Distortion Amplitude is –62 dBc and the Lower Distortion
Amplitude is –63 dBc, enter –62 dBc as the Worst Distortion
Amplitude.
28.Enter –17 dBm as the Mixer Level in Table 2-72 (–12 dBm input
power –5 dB input attenuation).
29.Calculate the equivalent TOI by subtracting one half of the Worst
