Triggering
To properly acquire data, that is, to use the instrument to sample a signal and
digitize it into a waveform record that you want to measure or otherwise process,
you need to set up the trigger conditions. This section provides background on,
and the procedures for using, the basic elements of triggering: source, holdoff,
mode, and so on. This section covers the following topics:
H
Triggering Concepts which describes some basic principles of triggering and
the following trigger elements: type , source , coupling , holdoff , mode ,
and so on
H
Triggering from the Front Panel which describes how to use the front-panel
triggering controls each of which is common to most of the trigger types the
instrument provides
H
Additional Trigger Parameters which describes how to access common
trigger functions in the Trigger control window
H
Advanced Triggering which describes trigger types that you can use to
isolate specific signal phenomena
H
Sequential Triggering which describes how to combine the A (Main) and B
(Delayed) trigger systems to capture unique events
H
Comm Triggering (optional on TDS7000 Series & TDS6000 Series) which
describes triggering on communications signals
H
Serial Pattern Triggering (optional on TDS7000 Series & TDS6000 Series)
which describes triggering on serial data patterns
