STRIP CHARTS
Chart displays are used to view stored traces. Only stored traces have a time history, thus, only stored traces
may be displayed on a chart. The full screen chart display is shown below. If the split screen format is used,
the chart will display half as many vertical divisions but will be the same as the full size display in all other
aspects.
The chart scaling can be changed in the
DISPLAY/SCALE menu. Both the vertical scale
(center value and range) and horizontal scale can
be changed. [AUTO SCALE] will automatically
adjust the vertical center and range to display all
of the data within the graph. [AUTO SCALE] will
not change the horizontal scale.
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
being displayed, use the cursor to pan right and
left within the buffer.
Offset and Expand
If the trace being shown is affected by a non-zero
offset or a non-unity expand, then the Offst and
Expd alert indicators are turned on.
Trace Identifier and Active Display
The chart is labelled with a trace identifier at the
upper left. This indicates which trace is being dis-
played. The trace definition is shown next to the
identifier. If this display is the active display, the
trace identifier will be in inverse. When a chart is
the active display, the [AUTO SCALE] key will
scale the chart so all of the displayed data is on
the graph. In addition, when a chart is the active
display, pressing the [CURSOR] key will activate
the cursor.
Chart Scaling
The graph vertical range is the center value plus
and minus the range. The center value is the value
of a data point located at the vertical midpoint of
the graph. The horizontal scale is the number of
seconds per division across the graph. The time
value of the right most point is shown at the
bottom right. When the most recent point is at the
right, the time shown will be 0.000 S.
