5.3.4 Discrete Waveform Graph Tool

The Discrete Waveform Graph Tool displays the data for discrete input channels in the MAQ

20 data

acquisition system. The X-axis represents the number of samples collected from the system and is

shown at the top of the display and the Y axis shows the logic states 0 or 1 for the channels. Data can be

displayed or hidden using the +/- box at the top left corner of the plot. The horizontal hash mark in the left

hand legend represents the midscale value for each channel for determination of channel low/high state.

To change the Discrete Waveform Graph Tool properties, double click on the device to open the

Properties window. Only the Appearance, Graph, Layout and Scroll Bar categories contain parameters

that are useful to modify when interfacing to the MAQ

20.
