Trigger Function
11.1 Overview
(1) The term "trigger" refers to a signal which determines the
timing to start or stop recording or internal data capture.
(2) There are three types of signal which can be used for
triggering (trigger sources):
Internal trigger [channel 1 (A), channel 2 (B)]
The trigger is derived from the analog input signals to
channels 1 and 2 or the logic inputs to channel groups A
and B. The trigger function monitors the state of the
signals, and is activated when a predetermined signal
state occurs.
External trigger
Triggering occurs when the EXT TRIG terminals are
shorted, or when the input voltage drops below about
2.5 V. This is used for synchronization to other
apparatus. This is also used for operation of several 8804
units synchronized in parallel.
Timer trigger [ timer ]
The timer trigger occurs between predetermined times for
starting and stopping operation. Use the timer trigger for
fixed time recording.
