Executing Measurement

This chapter describes how to generate a trigger to start measurement. It also
provides helpful information for measurement.

Starting (Triggering) Measurement

The method used to start (trigger) measurement varies depending on the setup
of the trigger mode, as shown in
Table 6-1 Trigger mode
Trigger mode
Internal trigger (INT)
Manual trigger (MAN)
External trigger (EXT)
BUS trigger (BUS)
E4981A ignores any trigger that is input during the measurement cycle. Be
sure to trigger the instrument when it is not in a measurement cycle.
Table 6-1 below:
Method to generate a trigger
The internal trigger is used to generate a trigger.
Pressing the [Trigger] key on the front panel generates a
trigger.
Inputting an external trigger signal through the Ext Trig
terminal, handler interface, or scanner interface generates a
trigger.
The E4981A performs one cycle of measurement each time it
receives a trigger command sent via GPIB/LAN/USB.
