Making Measurements Using Spectrum Analyzer Mode
Using the Time-Gated Spectrum Analyzer Capability Without the Gate Utility (Option 107 only)
Example
of
a
Time-Gated
Pulsed
RF
Signal
The measurement procedures in this section explain how to use the time
gate capability without the convenience of the Gate Utility functions. The
Gate Utility provides the user with simultaneous displays of the frequency
and time domain to assist in setting up and manipulating the time gate. An
oscilloscope is not needed when using the Gate Utility. A list of all the Gate
Utility keys can be found under the
@FiEEF]
key in the key menus in Chapter
7. Descriptions of the different Gate Utility functions are found in Chapter 6.
NOTE
This example only applies to using time-gated spectrum analyzer capability with a pulsed RF signal. For
more information on using Option 107 to view other types of signals, see product note 8590-2.
The following example demonstrates the rules for setting up a time-gated
measurement. In this example, we are using two signal generators to
generate two signals at the same frequency (50 MHz). The pulse generators
“space” (interleave) the signals in time as well as pulse modulate the signals.
