GTSRC Set Profile Trigger source TRIGGER

Syntax: GTSRC <source>

source: INTA INTB EXTTTL MANUAL CONT

Remarks: INTA = internal sensor A

INTB = internal sensor B

EXTTTL = external BNC TTL trigger input

MANUAL = manual push button trigger

CONT = continuous

MANUAL trigger only functions correctly on non-repetitive sampling, i.e., the PROFILE PERIOD needs to be 6ms or greater.

The display shows an ‘x’ marking the trigger point. This trigger point mark rotates as the profile data is updated, changing between 'x' and '+' on each data update. On rapid updates, the trigger point mark may appear like a star (*), as it is rotating so quickly. In manual, external or GPIB triggered displays, the mark rotates at a slower rate and each true data update can be seen.

The GTSRC setting is overridden by the Group Execute Trigger GPIB com- mon command (GET), *TRG, TR0, TR1 and TR2 commands. The TR3 command will return the system to its previous state if the TR0 (Trigger hold) command has been used.
