Syntax

TARM

Syntax
T is an abbreviation for the TRIG command.
T [event]
Refer to the TRlG command for more information.
Trigger arm. Defines the event that enables (arms) the trigger event (TRIG
command). You can also use this command to perform multiple measurement
cycles.
TARM [event][,number_arms]
event
The event parameter choices are:
Numeric
event Query
Parameter Equiv.
AUTO 1
EXT 2
SGL 3
HOLD 4
SYN 5
Power-on event = AUTO.
Default event = AUTO.
number_arms
The number_arms parameter is valid only with the SGL trigger arm event; in this
case, the valid range is 0 - 2.1E+9. Specifying 0 or 1 with the SGL event has the
same effect as using the default value (1): the trigger is armed once and then reverts
to the HOLD state (disabled). When you specify a number greater than 1 as the
number_arms parameter, you have selected "multiple arming." In multiple
arming, the multimeter generates enough single trigger arms to satisfy the
number_arms parameter. Refer to "multiple arming" in the Remarks section
below for more information.
Power-on number_arms = 1 (multiple arming disabled)
Description
Always armed
Arms following a low-going TTL transition on the Ext
Trig connector. (Executing TARM EXT clears the
trigger buffer if TBUFF is ON).
Arms once (upon receipt of TARM SGL) then becomes
HOLD
Triggering is disabled
Arms when the multimeter's output buffer is empty,
reading memory is off or empty, and the controller
requests data.
