Making Measurements Using Spectrum Analyzer Mode

Using the Time-Gated Spectrum Analyzer Capability Without the Gate Utility (Option 107 only)

Using the Time-Gated Spectrum Analyzer Capability to View Pulsed RF

This example demonstrates how to use time-gated spectrum analyzer capability to view two different pulsed RF signals. The signals are at the same frequency, but they interleave in time. (This example uses the time gate function without using the gate utility.)

To use time-gated spectrum analyzer capability to view the amplitude of a pulsed RF signal accurately, the spectrum analyzer settings of the sweep time, resolution bandwidth, video bandwidth, gate delay, and gate length must

be set correctly. To set the spectrum analyzer settings correctly, you must determine the pulse repetition interval, pulse width, and signal delay (if any) of the pulsed RF signal. Figure 5-18 shows an example of two pulsed RF signals.
