Working With Traces

Traces are the visible representations of waveforms that appear on the display grid. They may show
live inputs (Cx, Digitalx), a math function applied to a waveform (Fx), a stored memory of a waveform
(Mx), a zoom of a waveform (Zx), or the processing results of special analysis software.
Traces are a touch screen object like any other and can be manipulated. They can be panned, moved,
labeled, zoomed, and captured in different visual formats for printing/reporting.
Each visible trace will have a descriptor box summarizing its principal configuration settings. See
OneTouch Help for more information about how you can use traces and trace descriptor boxes to
modify your configurations.

Active Trace

Although several traces may be open, only one is active and can be adjusted using front panel
controls and touch screen gestures. A highlighted descriptor box indicates which trace is active. All
actions apply to that trace until you activate another. Touch a trace descriptor box to make it the
active trace (and the foreground trace in that grid).
Active trace descriptor (left), inactive trace descriptor (right).
Whenever you activate a trace, the dialog at the bottom of the screen automatically switches to the
appropriate setup dialog.
Active descriptor box matches active dialog tab.

Foreground Trace

Since multiple traces can be opened on the same grid, the trace shown on top of the others is the
foreground trace. Grid indicators (matched to the input channel color) represent values for the
foreground trace.
Touch a trace or its descriptor box to bring it to the foreground. This also makes it the active trace.
Note that a foreground trace may not be the same as the active trace. A trace in a separate grid may
subsequently become the active trace, but the indicators on a given grid will still represent the
foreground trace in that group.
