Configuring Pulse Modulation - Keysight M9383A Programming Manual

Configuring Pulse Modulation

The M9312A Source Output module features a pulse generator that supports the
modulation of the carrier signal with these eight pulse modes: square pulse, free
run pulse, pulse train, doublet pulse, triggered pulse, triggered doublet pulse,
external pulse, and gated mode. The pulse output can be routed internally to
modulate the PIN diode in the RF signal path of the M9312A or drive an output
trigger to external hardware, or both.
For pulse modulation, you must have either of the following three hardware options
installed.
For more information about these hardware options, refer to the M9383A Startup
Guide
To configure Pulse Modulation programmatically, use the IKtMVsg.Modulation.
