3.6.11.17 SOURce:PULSe Subsystem
This subsystem contains the commands to set the pulse generator (option SM-B4). The pulse
generation is triggered on principle, with the trigger certainly being able to be set to "free run" using
TRIGger:PULSe:SOURce AUTO as well. The pulse modulation (option SM-B3) is set in the
SOURce:PULM subsystem.

Option SM-B4
[:SOURce]:PULSe:DELay 40 ns to 1 s
The command specifies the time from the start of the period to the first edge of the pulse. Due to
the construction of the instrument, this parameter is set to 0 if :SOURce:PULSe:DOUBle:STATe
is set to ON. The old value is activated again as soon as the double pulse has been switched off.
Example: :SOUR:PULS:DEL 10us *RST value is 1 us
[:SOURce]:PULSe:DOUBle
The commands to check the second pulse are under this node. If :SOURce:PULSe:
DOUBle:STATe is set to ON, a second pulse whose width is identical to the first pulse is
generated in every period.
[:SOURce]:PULSe:DOUBle:DELay 60 ns to 1 s
The command sets the time from the start of the pulse period to the first edge of the second
pulse. *RST value is 1 us
Example: :SOUR:PULS:DOUB:DEL 10us
[:SOURce]:PULSe:DOUBle[:STATe] ON | OFF
The command switches the second pulse on or off.
ON The second pulse is switched on. Parameter :SOURce:PULSe:DELay is set to 0
and cannot be changed. WIDTh > (PULSe:PERiod - PULSe:DOUBle:DELay)/2
results in error message -221, "Settings conflict".
OFF The second pulse is switched off. *RST value is OFF
Example: :SOUR:PULS:DOUB:STAT OFF
[:SOURce]:PULSe:PERiod 100 ns to 85 s
The command sets the pulse period.
The pulse period is the reciprocal value of the pulse frequency, thus this command is coupled to
command :SOURce:PULM:INTernal:FREQuency *RST value is 10 us
Example: :SOUR:PULS:PER 2s
[:SOURce]:PULSe:WIDTh 20 ns to 1s
The command sets the pulse width. *RST value is 1 us
Example: :SOUR:PULS:WIDT 0.1s
