Set the frequency of the signal generator as 1GHz and power as -20dBm. Connect the output of the signal
generator to the input port of the spectrum analyzer, as shown in Fig. 4-1. Set the repetition frequency of pulse
modulation as 1kHz and pulse width as 900ns. Enable the pulse modulation and RF output.
b) Set the spectrum analyzer:
The pulse RF signal is generally measured in the broad band mode. In order to prevent the influence of the video
filter on measurement results, the video bandwidth should be set as 3MHz.
Press [Reset] key.
Press [Frequency], [Center Frequency] and 1[GHz].
Press [frequency], [Span], 10[MHz], [sweep], [Sweep Time Auto Man] and 60[ms].
Press [BW], [RBW Auto Man], 100 [kHz], [VBW Auto Man] and 100 [kHz].
Press [BW], [Detector] and [Peak] to activate the peak detector.
Enable the center frequency function and adjust the span until the center side lobe and at least one pair of side
lobes appear on the screen, as shown in Fig. 4-20.

Increase the sweep time (decrease the sweeping speed) until the graph is filled into a solid line, as shown in Fig.
4-21. If the spectrum line cannot be filled, it indicates that the instrument is not in the broad band mode. In this case,
