Features and Functions
External Triggering
External triggering takes one reading (or the specified number of readings)
each time the multimeter receives a pulse on the rear–panel (coaxial)
Ext
Trig
terminal. You may select whether the multimeter uses the rising edge
(
POS
) or falling edge (
NEG
) of the applied external trigger signal to trigger a
reading
(see
. The diagram below shows the
Ext Trig
terminal and
NEG
timing:
•
The multimeter buffers one external trigger. If the multimeter is
currently taking a reading while another trigger occurs, that second
trigger is accepted. After the reading in progress is completed, the
stored trigger is issued.
•
The
Trig
annunciator turns on when the multimeter is waiting for an
external trigger.
•
The rear panel
VM Comp
(voltmeter complete) terminal provides a pulse
after completion of each measurement. Voltmeter complete and external
trigger implement a standard hardware handshake sequence between
measurement and switching devices. The diagram below shows the
VM
Comp
terminal and
NEG
timing:
•
Front Panel Operation:
The external trigger mode corresponds in function
to pressing the
key from the front panel, except that you apply
the trigger signal to the
Ext Trig
terminal.
•
Remote Interface Operation:
The following command selects the trigger
source from the external terminal:
TRIGger:SOURce EXTernal
