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.
