Using the Infiniium DCA
Introduction
Refer to the Help System
To learn how to use your Infiniium DCA and to locate information on specifica-
tions (including plug-in modules), instrument features, and measurement
configuration refer to Chapter 4, “Using the Built-In Informatio n System” in
this book.
You must provide a trigger input signal
Because high-speed oscilloscopes are not capable of triggering directly on a
test signal, you must first connect an external timing reference signal to the
front-panel trigger input connector. This input allows the Infiniium DCA to
synchonize to the input signal. You can select free-run triggering when an
external trigger is unavailable. However, you will onl y be able to view the
waveform for amplitude information only without any timing information. This
is an easy way to examine the amplitude of a signal.
