Term interpretation
1. Source: Trigger can occur from several sources: Input channels (CH1, CH2), Ext,
Ext/5.
Input: It is the most commonly used trigger source. The channel will work when
selected as a trigger source whatever displayed or not.
Ext Trig: The instrument can be triggered from a third source while acquiring data
from CH1 and CH2. For example, to trigger from an external clock or with a signal
from another part of the test circuit. The EXT, EXT/5 trigger sources use the external
trigger signal connected to the EXT TRIG connector. Ext uses the signal directly; it has
a trigger level range of -0.6 V to +0.6 V. The EXT/5 trigger source attenuates the
signal by 5X, which extends the trigger level range to -3 V to +3 V. This allows the
oscilloscope to trigger on a larger signal.
2. Trigger Mode:
The trigger mode determines how the oscilloscope behaves in the absence of a trigger
event. The oscilloscope provides three trigger modes: Auto, Normal, and Single.
Auto: This sweep mode allows the oscilloscope to acquire waveforms even when it
does not detect a trigger condition. If no trigger condition occurs while the oscilloscope
is waiting for a specific period (as determined by the time-base setting), it will force
itself to trigger.
