NORMal Input Direction is turned off and the input pulse signal is TTL high level.
INVerted Input Direction is turned on and the input pulse signal is TTL low level.
Example: :PULM:ENTernal:POLarity INV External input pulse signal is inverted to TTL low level.
Reset status: NORM

[:SOURce]:PULM:INTernal:DELay <DelayTime>
Function: This command is used for setting the pulse delay of the pulse modulation. The actual
settable maximum delay depends on the current pulse period set by the user. In
addition, it should be noted that, the set pulse delay is valid only when the pulse
source is set to Auto, Square, D-Pulse or Trig. And when it is set to Trig, there is
100ns inherent delay in the pulse delay. For related commands, see the commands

:PULM:INTernal:PERiod

:PULM:SOURce
‖.
Setting format: [:SOURce]:PULM:INTernal:DELay <val>
Query format: [:SOURce]:PULM:INTernal:DELay?
Parameter:
<DelayTime> Pulse delay time of pulse modulation.
Non-Trig Mode: 0s[0ns
，
42.000000000s],
Trig Mode: 0s[100ns
，
42.000000000s].
Example: :PULM:INTernal:DELay 1ms Set pulse delay to 1 ms
Reset status: 0s

[:SOURce]:PULM:INTernal:FREQuency <Frequency>
Function: This command sets PRF of pulse modulation. When the pulse source is set to Square,
the duty ratio of the pulse signal output is 50%. This command may be used for
changing the frequency of the square signal. For setting pulse source, see the
command ―
:PULM:SOURce
‖.
Setting format: [:SOURce]:PULM:INTernal:FREQuency <val>
Query format: [:SOURce]:PULM:INTernal:FREQuency?
Parameter:
<Frequency> PRF of pulse modulation.
Range: 1kHz [0.023Hz
，
25MHz]
Example: :PULM:INTernal:FREQuency 1MHz Set PRF to 1 MHz.
Reset: 1kHz

[:SOURce]:PULM:INTernal:PERiod <Period>
Function: This command sets the period of pulse signal generated inside the signal generator. If
the set period is smaller than or equal to the current pulse width, the pulse width will
be automatically adjusted to be smaller than pulse period. For setting pulse width, see
the command ―
:PULM:INTernal:PWIDth
‖.
