To make other Pulse settings, such as enabling the internal pulse modulators, use this command:

• SENSe<ch>:PATH:CONFig:ELEMent[:STATe] <elem>, <setting>

• At that command help topic, click the IF Configuration elements and values link to see the Pulse element and setting (in the middle box ) to configure.

Pulse Definitions

• D = Delay; the time before each pulse begins

• W = Width; the time the pulse is ON

• P = Period; one complete pulse cycle

• Duty Cycle = W/P

Important: If D + W is greater than P, then undefined VNA behavior results. There is NO error message or warning.

Applicable Models: All with Pulsed RF Measurement Option

(Read-only) Returns the string names of internal and configured external pulse generators.

Parameters
