Fluke PM6681 manual Triggering, Backward Traversing an Event-detection Layer, TRG Trigger Command

Using the Subsystems

layer). This delay can be programmed by using the <layer>:DELay command.

￿Backward Traversing an Event-detection Layer

The number of times a layer event has to initiate a device action can be pro- grammed by using the <layer>:COUNt

command. For example: :TRIGger:COUNt 3 causes the in- strument to measure three times, each measurement being triggered by the spec- ified events.

￿*TRG Trigger Command

The trigger command has the same func- tion as the Group Execute Trigger com- mand GET, defined by IEEE 488.1.

When to use *TRG and GET

The *TRG and the GET commands have the same effect on the instrument. If the Counter is in idle, i.e., not parsing or exe- cuting any commands, GET will execute much (≈ 20 ∝s) faster than *TRG (≈ 4 ms) since the instrument must al- ways parse *TRG.
