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 below:
Table 6-1 Trigger mode
Trigger mode Method to generate a trigger
Internal trigger (INT) The internal trigger is used to generate a trigger.
Manual trigger (MAN)
Pressing the [Trigger] key on the front panel generates a
trigger.
External trigger (EXT)
Inputting an external trigger signal through the Ext Trig
terminal, handler interface, or scanner interface generates a
trigger.
BUS trigger (BUS) The E4981A performs one cycle of measurement each time it
receives a trigger command sent via GPIB/LAN/USB.
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.
