TRIGger:TIMer
Syntax
TRIGger:TIMer {<seconds>|MIN|MAX|DEF}
TRIGger:TIMer? [{MIN|MAX}]
Description
This command sets the trigger-to-trigger interval (in seconds) for measurements on the channels in the present scan list. This command defines the time from the start of one trigger to the start of the next trigger, up to the specified trigger count (see TRIGger:COUNt command).
Used With:
34921A through 34925A Multiplexer Modules
34950A Digital I/O Module (digital input and counter channels only)
34952A Multifunction Module (digital input and totalizer channels only)

Remarks
The scan interval applies to the TIMer trigger source as set by the TRIGger:SOURce command.
For the multiplexer modules, the internal DMM is required. An error is generated if the internal DMM is disabled (see INSTrument:DMM[:STATe] command) or not installed in the mainframe.
If the scan interval is less than the time required to measure all channels in the scan list, the instrument will scan continuously, as fast as possible (no error is generated).
The CONFigure and MEASure? commands automatically set the trigger interval to 1 second and the scan count to 1 sweep.
The instrument clears all readings from memory when the triggering configuration is changed.
The instrument sets the scan interval to immediate (0 seconds) after a Factory Reset (*RST command). An Instrument Preset (SYSTem:PRESet command) or Card Reset (SYSTem:CPON command) does not change the setting.
Return Format
The query command returns the scan interval in seconds in the form "+1.00000000E+00".
Examples
The following program segment sets the trigger interval to 30 milliseconds.
TRIG:SOUR TIMER
TRIG:TIM 30E-03
The following query returns the trigger interval in seconds.
TRIG:TIM?
Typical Response: +3.00000000E-02
