4.21 Source Subsystem - Pulse

This subsystem controls the generation of output pulses. The PULSe:DCYCle, PULSe:HOLD,
PULSe:PERiod, and PULSe:WIDTh commands are coupled, which means that the values
programmed by any one of these commands can be affected by the settings of the others. Refer
to the tables under PULSe:HOLD for an explanation of how these commands affect each other.

Subsystem Syntax

[SOURce:]

PULSe

:COUNt | INFinity

Selects transient pulse count

:DCYCle

Selects pulse duty cycle

:HOLD WIDTh |DCYCle

Selects parameter that is held constant

:PERiod

Selects pulse period when the count is greater than 1

:WIDTh

Selects width of the pulses

PULSe:COUNt

This command sets the number of pulses that are output when a triggered output transient
occurs. The command accepts parameters in the range 1 through 2E8. If INFinity or MAXimum is
sent, the output pulse repeats indefinitely.

Command Syntax

[SOURce:]PULSe:COUNt | INFinity

Parameters

1 to 2E8 | MINimum | MAXimum | INFinity

*RST Value

1

Examples

PULS:COUN 3 PULS:COUN MIN PULS:COUN INF

PULS:DCYC PULS:HOLD PULS:PER PULS:WIDT

PULSe:DCYCle

This command sets the duty cycle of the triggered output pulse. The duty cycle units are specified
in percent.

Command Syntax

[SOURce:]PULSe:DCYCle

Parameters

0 to 100%|MINimum|MAXimum

*RST Value

50%

Examples

PULS:DCYC 75 PULS:DCYC MAX

PULS:COUN PULS:HOLD PULS:PER PULS:WIDT

PULSe:HOLD

This command specifies whether the pulse width or the duty cycle is to be held constant when the
pulse period changes. The following tables describe how the duty cycle, period, and width are
affected when one, two, or all three parameters are set in a single program message.
