SINGLE and DUAL TRACE DISPLAYS
The screen can be formatted as a single trace
(Single) display or a dual trace (Up/Down) display.
The screen format is selected in the DISPLAY/
SCALE menu. There are three displays which may
be configured, the Single screen display and the
Top and Bottom displays for the split screen. Each
display can show a different trace using a separ-
ate display type.
There are three different display types - Bar (with
large numbers), Polar, and Chart (of stored traces
only). The Bar graph resembles a "normal" lock-in
display. The Polar graph plots X and Y on a circu-
lar graph to illustrate the signal as a vector relative
to the reference. The Chart displays stored data in
a strip chart form, complete with zooming, panning
and cursor. In order to use the analysis functions
such as curve fitting, the data must be stored in
the buffer and displayed in a strip chart.
The default screen (pg. 4-5) is a dual trace display
where the top display shows Trace 1 (X) and the
bottom display shows Trace 2 (Y). Both displays
are bar graphs.
Remember, only data traces may be displayed.
The traces are defined in the TRACE/SCAN
menu. The choices of which traces are displayed,
and in which formats, are selected in the
DISPLAY/SCALE menu.
A dual trace screen showing both Bar and Chart
displays is shown below. Each display is labelled
with a trace identifier indicating which trace is
being displayed. The trace definition is also
shown. In the screen below, the top display is
showing Trace 1 which is defined to be X.
One of the displays is the active display. The
active display is denoted by displaying the trace
identifier in inverse video (bottom display below).
Certain functions, such Auto Scale and cursor
movement, affect the active display only. The
[ACTIVE DISPLAY] key is used to switch the
active display between the top and bottom dis-
plays. A full screen display is always the active
display.
