Working With Traces
Trace Descriptor Boxes
Channel (C1-C4), Zoom (Z1-Z8), Math (F1-F8), Memory (M1-M4), and
Digital (Digital1-Digital4, on -MS models) descriptor boxes appear along
the bottom of the grid area when a trace is turned on. Descriptor boxes
summarize, activate, arrange, and configure the traces they represent.
Trace Context Menu
The trace context menu is a quick way to apply math, measurements, or
labels to traces. To open the context menu, right-click with your mouse or
touch-and-hold on the trace descriptor box until a white circle appears,
then release.
Active vs. Inactive Trace
Although several traces may be open and appear on the display, only one at
a time is
active
. This is true for all traces, regardless of the type. All actions
apply to the active trace until another is selected.
Touch a trace or its descriptor box to
activate
it and bring it to the
foreground
.
When the descriptor box appears highlighted in blue, front panel controls and
touch screen gestures apply to that trace.
Active.
Controls will work
for this trace.
Inactive.
Controls will not
work for this trace.
Adjusting
On setup dialogs, many entries can be made by selecting from the pop-
up menu that appears when you touch a control. But when an entry field
appears highlighted in blue after touching, it is
active
and the value can be
modified by turning the front panel knobs. Fields
that don’t have a dedicated knob (as do Vertical
Level or Horizontal Delay) can be modified using
the Adjust knob.
If you have a keyboard installed, you can type
entries in an active (highlighted) data entry
field. Or, you can touch again, then “type” the
entry by touching keys on the virtual keypad
or keyboard.
To use the virtual keypad, touch the soft keys
exactly as you would a calculator. When you
touch OK, the calculated value is entered in
the field.
