Turning On/Off Traces
From the Front Panel
Press the corresponding Channel button (1–4) to turn on a trace and make
it active. To turn off an active trace, press the button again.
A trace (waveform pattern) appears on the grid with a color-coded Channel
descriptor box below it. This box always displays the current settings for the
trace and is labeled C1–C4.
To open digital traces (-MS models only), press the Dig button. Digital trace
descriptors are labeled Digital1-Digital4.
From the Display
Choose Vertical > Channel<#> Setup to turn on the trace and make it
active. To turn off the trace, touch the descriptor box, then clear the Trace
On checkbox on the Channel dialog.
For digital traces, choose Vertical > Digital<#> Setup. Turn off the trace by
clearing the Group checkbox.
Zoom, Math, and Memory Traces
In addition to the channel and digital traces, you can view a zoom (close-up
portion) of a trace (Z1-Z4), a trace previously stored to the oscilloscope’s
memory (M1-M4), or a trace that displays the result of a math function
applied to one or more source traces (F1-F2). The quickest way to turn
on these traces is to use the front panel Zoom, Math, and Memory
buttons, which open the corresponding trace setup dialogs. Adjust a trace
individually by touching its descriptor box and changing dialog settings.
If multiple channel traces are open and you press Zoom, zoom traces are
created for each channel.
Active vs. Inactive Trace
A highlighted descriptor box indicates the “active” trace, and all display and
front panel actions will apply to that trace until another is selected. This is
true for all traces, regardless of the type. Although several traces may be
open and appear on the grid, only one at a time is active.
Also, the front panel Channel buttons (1-4) and the Dig, Mem, Zoom, and
Math buttons will light up to indicate the active trace.
Viewing Multiple Traces
By default, the oscilloscope has Auto Grid enabled. This divides the screen
into a maximum of three grids, one each for channels/memories, math
functions, and zooms. All traces of the same type appear on the same grid.
To display all types of traces on a single grid, choose Display > Single Grid
from the menu bar
Two special grid layouts are available: XY Grid, which puts the oscilloscope
in XY mode, and XY Single Grid, which creates one XY grid and one single
grid for the rest of your traces.
Active. Controls will
work for this trace. Inactive. Controls will not
work for this trace.
