In ATM3500A, you can specify the trigger source to be one of these
three options: front panel operations, external hardware trigger source
and remote interface operations.
Front Panel Operation
Use the front panel buttons - AUTO TRIGGER for auto triggering and
SINGLE for single triggering.
External Hardware
You apply a trigger pulse to the Ext TRIG (BNC) terminal on the rear
panel. External hardware triggering is like using single trigger but the
trigger source is an external hardware. When the multimeter receives
a pulse from the trigger source, it takes one reading, or a specified
number of readings. To set the external hardware trigger, press both
the SHIFT + SINGLE buttons to enable external hardware trigger. The
lit “EXT” annunciator on the display indicates the enabling of the
external hardware trigger.
External Triger Terminal
You can trigger the ATM3500A by using a low-true pulse to the Ext Trig
(external trigger) terminal located on the rear panel. And to use this
terminal via the remote interface, you have to select the external
trigger source by using the TRIGer:SOURce EXTernal command.
Note: You can use a simple switch to generate an external trigger by
※
using the Ext Trig input as shown in the following.
