connectors, or the connectors will be damaged.
Procedure
1. Set the synthesized signal generator to output a 500 MHz, −10 dBm,
CW signal. Set the AM and FM controls to off.
75 Ω Input only: Set output level to −4dBm.
2. Set the function generator to output a 2 kHz, 1.14 Vp-p triangle
waveform signal.
3. Connect the equipment as shown in Figure 2-11.
4. Press Preset on the analyzer. Press the Factory Preset softkey, if it is
displayed. Set the analyzer by pressing the following keys:
FREQUENCY, 500 MHz
SPAN, 10 MHz
SPAN, Span Zoom, 50 kHz
5. Wait for the Span 50 kHz message to appear. Set Signal Track (Off).
6. Set the span to 0 Hz and set the analyzer as follows:
BW/Avg, Res BW, 3MHz
Sweep, Sweep Time, 5 ms
AMPLITUDE, Scale Type (Lin)
Peak Search (or Search)
More, Search Parameters (or Search Criteria)
Peak Excursion, 3 dB
Adjust the synthesized signal generator amplitude as necessary for a
mid-screen display (marker amplitude should read approximately
110 mV).
7. Set the synthesized signal generator modulation source to EXT DC.
Set AM ON at 90% modulation.
8. On the analyzer, press Trig then Video. Set the video trigger level to
110 mV (mid-screen).
9. On the analyzer, press Single. After the completion of the sweep,
press Peak Search (or Search), 0, s, Meas Tools, Next Pk Right. This is
the marked signal.
10.Press Marker, Delta, then Peak Search (or Search) and press
Next Pk Right eight times so the delta marker is on the eighth signal
peak from the marked signal.
11.Read the marker delta (∆ Mkr1) time. Calculate the sweeptime
