Introduction

This chapter describes how to display a waveform in
View Display Mode and how to plot and interpret
measurement data over time in TrendGraph™
Display Mode.

View Display Mode Basics

The GMM must know when to begin displaying
(trigger) a waveform. Triggering requires that a valid
signal level is specified, a direction for that signal
(positive going or negative going) is selected, and
the trigger signal source (internal or external) is set.
Setting the range for the vertical divisions and the
timebase for the horizontal divisions directly

influences the proportions and legibility of the
triggered waveform.
The type of waveform acquisition may also be
important. A continuous, internal trigger enables an
ongoing display of the input signal whenever you
turn the selector to a new function.
Using Full Auto
"Full Auto" allows the GMM to automatically select
the Trigger Level, Trigger Slope, Trigger Source,
Range, and Time Base necessary for an optimum
display of the input signal. If a good input is present,
you will see a waveform that nearly fills the screen.
