Turning On/Off Traces

From the Front Panel

Press the corresponding Channel button (1–4) to turn on the 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.

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 and deselect Trace On.

Zoom, Math, and Memory Traces

Besides the channel traces, you can view a zoom (close-up) of a portion

of the channel trace (Z1-Z4), a channel 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 channel 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 setup dialogs. If multiple channel traces are open

and you press Zoom, zoom traces are created for each channel. Adjust a

trace individually by touching its descriptor box and changing dialog settings.

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.

The same is true for all math, zoom, and memory traces. 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 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.
