Analyzer Setup - Keysight X Series Measurement Manual

Step 2. Set up ESG #1 to transmit a pulsed-RF signal with frequency modulation. Set the
FM deviation to 1 kHz and the FM rate to 50 kHz:
ESG #1 generates the pulsed FM signal by frequency modulating the carrier signal
and then pulse modulating the FM signal. The pulse signal created in step 1 is
connected to the EXT 2 INPUT (on the front of ESG #1). The ESG RF OUTPUT is
the pulsed-RF FM signal to be analyzed by the spectrum analyzer.
