Generating a Pulsed-RF FM Signal

Generating a Pulsed-RF FM Signal
When performing these measurements you can use a digitizing oscillascope or your
Keysight X-Series Signal Analyzer (using Gate View) to set up the gated signal.
Refer back to these first three steps to set up the pulse signal, the pulsed-RF FM
signal and the oscilloscope settings when performing the gated LO procedure

Signal source setup

Step 1. Set up the pulse signal with a period of 5 ms and a width of 4 ms:
There are many ways to create a pulse signal. This example demonstrates how to
create a pulse signal using a pulse generator or by using the internal function
generator in the ESG.See
you are using a second ESG. Select either the pulse generator or a second ESG to
create the pulse signal.
