[SOURce]:PULM:INTernal:PERiod?

This command sets the pulse period for the internally generated pulse modulation using the variables

<value>.

If the entered value for the pulse period is equal to or less than the value for the pulse width, the pulse

width changes to a value that is less than the pulse period.

*RST 2.5 ms

Range 200 ns – 10 s

:PULM:INTernal:PWIDth

[SOURce]:PULM:INTernal:PWIDth <num>

[SOURce]:PULM:INTernal:PWIDth?

This command sets the pulse width for the internally generated pulse signal.

This command sets the pulse width for the internally- generated pulse modulation using the variable

<num>.

If the entered value for the pulse width is equal to or greater than the value for the pulse period, the

pulse width changes to a value that is less than the pulse period.

*RST 1.25 ms

Range 50 nS to PERiod

:PULM:SOURce

[SOURce]:PULM:SOURce INTernal|EXTernal|BITStream

[SOURce]: PULM:SOURce?

If set

*RST INTernal

:PULM:STATe

[SOURce]:PULM:STATe ON|OFF|1|0

[SOURce]:PULM:STATe?

This command enables or disables pulse modulation for the selected path.

*RST 0

:PULM:MODE

[SOURce]:PULM:MODE FIXed | LIST

[SOURce]:PULM:MODE?

This command sets the modulation mode. With “FIXed”, the normal ON/OFF modulation can be

performed. With LIST, an arbitrary bit pattern can be loaded that will be used to modulate the carrier.

LIST mode is available with pulse train option.

*RST FIXed
