How to create Uncoupled Markers
To create markers that are NOT coupled (move independently on each trace):
—Press Marker
— Then More
— Then Coupled Markers OFF
Marker Colors
As shown in the above image, in NA and CAT Modes, markers are the same color as the trace to
which they are assigned. In SA Mode, the marker color is NOT the same as the trace.
Marker colors can NOT be changed.
Marker Trace (CAT, NA, NF Modes)
The Marker Trace setting is used to move markers between the data trace and memory trace.
When Coupled Markers is ON, this setting applies to the active marker for ALL traces that are
coupled. Otherwise, this setting applies to the active marker on only the active trace.
How to move a marker between traces
— With at least one marker present, press Marker then More.
— Then select the marker to move using Marker 1,2,3,4,5,6
.
— Then toggle Marker Trace Auto Data Mem
.
— Auto - Marker resides on data trace when it is visible. Marker resides on memory trace
when only IT is visible (Default setting).
— Data - Marker resides on data trace, even when not visible.
— Mem - Marker resides on memory trace, even when not visible.
Marker Trace (IQA and SA Mode)
Marker Trace determines the trace number on which a marker resides. A marker is created on, or
can later be changed to, the trace number specified by the Marker Trace selection. When changed,
a marker moves to the same X-axis location on the specified trace.
Learn more about IQA Traces in “Trace Display States (IQA Mode)” on page 284.
Learn more about SA Traces in “Trace Display States (SA Mode)” on page 141.
Markers are coupled by default.
