SOURce:PULSe Subsystem
This subsystem contains the commands to set the pulse generator (Option R&S SML-B3). The pulse
generation is triggered on principle, with the trigger certainly being able to be set to "free run" using
TRIG:PULS:SOUR AUTO
as well.

Option R&S SML-B3
[:SOURce]:PULSe:DELay 20 ns to 1.3 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
[:SOUR]:PULS:DOUB:STAT
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 T s
[:SOURce]:PULSe:DOUBle
The commands to check the second pulse are under this node. If
[:SOUR]:PULS:DOUB:STAT
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 1.3 s
The command sets the delay time from the start of the pulse period to the first edge of the second
pulse.
Example:
:SOUR:PULS:DOUB:DEL 10us
*RST value is 1 T s
[:SOURce]:PULSe:DOUBle:STATe ON | OFF
The command switches the second pulse on or off.
ON The second pulse is switched on.
Parameter
[:SOUR]:PULS:DEL
is set to 0 and cannot be changed. WIDTh >
(
PULS:PER - PULS:DOUB:DEL
)/2 results in error message -221, "Settings conflict".
OFF The second pulse is switched off.
Example:
:SOUR:PULS:DOUB:STAT OFF
*RST value is 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
[:SOUR]:PULM:INT:FREQ
.
Example:
:SOUR:PULS:PER 2s
*RST value is 10 T s
