Display and Scale Menu
Seconds/div Chart graphs have a horizontal scale which determines how much of the
data buffer will be displayed. The horizontal scale is the number of sec-
onds per division across the graph. By changing the horizontal scale, the
entire trace buffer can be displayed at once or a small portion may be
expanded. If only a portion of the buffer is displayed, use the cursor to
pan right and left within the buffer. To activate the cursor, select the chart
as the active display and press [CURSOR].
The horizontal scale may be set from 2 ms/div to 100 ks/div. If the scale
is such that the amount of time across the graph is less than 1/sample
rate, there may not be any data points on the graph.
