TRIGger:SLOPe{POSitive|NEGative}(?)
Description
The trigger slope command selects the sensitive edge of the trigger signal that is applied to the TRIG IN
connector. The Model 5251 can be made sensitive to either the positive or negative transitions. Positive
going transitions will trigger the generator when the POS option is selected. Negative transitions will trigger
the generator when the NEG option is selected. In Gated mode, two transitions in the same direction are
required to gate on and off the output. The trigger slope command will affect the generator only after it has
been programmed to operate in interrupted run mode. Modify the 5251 to interrupted run mode using the
init:cont off command.
Parameters
Name Type Default Description
POSitive Discrete POS Selects the positive going edge.
NEGative Discrete Selects the negative going edge.
Response
The 5251 will return POS, or NEG depending on the selected trigger slope setting.
RETRigger{OFF|ON|0|1}(?)
Description
This command will toggle the re-trigger mode on and off. This command will affect the 5251 only after it will
be set to INIT:CONT OFF.
Parameters
Name Type Default Description
OFF Discrete OFF Turns the re-trigger mode off.
ON Discrete Enables the re-trigger mode.
Response
The 5251 will return OFF, or ON depending on the selected option.
RETRigger:Time<time>(?)
Description
This parameter specifies the amount of time that will elapse between the end of the delivery of the waveform
cycle and the beginning of the next waveform cycle. Re-trigger can be initiated from any of the selected
advance options. The re-trigger command will affect the generator only after it has been programmed to
operate in interrupted run mode. Modify the 5251 to interrupted run mode using the init:cont off command.
Parameters
Name Range Type Default Description
<time> 200e-9 to 20 Numeric 200e-9 Programs the re-trigger period.
Response
The 5251 will return the present re-trigger period value.
