SYNTAX

Pstart,

Set the trigger start and/or stop times for an acquisition configured f or s tart

and/or stop on absolute time, where start and stop are in the standard

time/date stamp format: HH:MM:SS:T,mm/dd/yy where H is hours,

MM is minutes, SS is seconds, T is tenths of a second, mm is m onth,

dd is day, and yy is year.

P?

Query current start and stop times in the form: Pstart,stop

DESCRIPTION

The Program Trigger Times (P) command may be used to set the trigger start and/or s top times for an

acquisition that is configured for start and/or stop on Absolute Time as c onfigured by the Set Trigger

Configuration (T) command.

The Program Trigger Times command is to be used in concert with the Set Trigger Configurati on c ommand when

it is desired to begin and/or stop an acquisition on certain times and/or dates. The values of the start and stop

times are only used when the start and/or stop events have been configured for Absolute Time.

If only the start time is needed, the stop argument should be set to 00:00:00.0,00/00/00. Likewise, if

only the stop time is needed, the start argument should be set to 00:00:00.0,00/00/00.

In addition to the ability to start/stop on a particular time/date the unit has the ability to start / s top at a particular

time, independent of the date. If the date for the start/stop tim e is of no concern, then the date portion of the

time/date field should be set to 00/00/00. In this way, the unit can start or st op an acquisition at a particular

time regardless of the date. This feature is particularly useful when using the auto-rearm feature of the unit since

it will allow the collection of data at a particular time each day without user intervention.
