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 Information 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 only 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.
