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.

SENSe:PULSe:CATalog?

Applicable Models: N524xB (Read-only) Returns the string names of internal and configured external pulse generators.
Parameters	None
Examples	SENS:PULS:CAT?
Default	Not Applicable

SENSe<ch>:PULSe<n>:DELay <value>[,<name>]

Applicable Models: N524xB (Read-Write) Sets the pulse delay. The amount of time before a new pulse begins. See Pulse Definition diagram.
Parameters
<ch>	Any existing channel number; if unspecified, value is set to 1.
<n>	Internal pulse generator number. Choose from 0 to 4. 0 is the generator that pulses the ADC.
<value>	Delay value in seconds. Choose a value from about 33ns to about 70 seconds.
<name>	Optional. String name of the pulse generator. Required for use with external pulse generators. Use SENSe:PULSe:CAT? to return the names of configured pulse generators. If specified, <n> is ignored. If unspecified, <n> is required for internal pulse generators.

SENSe<ch>:PULSe<n>:DINCrement <value>[,<name>]

Applicable Models: N524xB (Read-Write) Sets the pulse delay increment. The delay increments with each pulse by the <value> amount. For example, in this diagram the delay starts as 1. On the second pulse, delay=2. On the third pulse, delay=3. Important: If D + W is greater than P, then undefined VNA behavior results. There is NO error message or warning. Delay includes the incremented value. This is useful for pulse profiling. See Pulse Definition diagram.

<n>	Pulse generator number. Choose from 0 to 4. 0 is the generator that pulses the ADC.

Note: The pulse output must be on using SENSe:PULSe4[:STATE] ON to view ADC activity.
Parameters
<ch>	Any existing channel number; if unspecified, value is set to 1.
<bool>	Choose from: ON (or 1) - Pulse 4 output pin indicates ADC activity. OFF (or 0) - Pulse 4 output pin indicates legacy behavior (pulse generator number 4 output).

Return Type	Boolean
Default	OFF

SENSe<ch>:PULSe:PERiod <value>[,<name>]
