Figure 7-3: Marker element in 4-bit binary format bit order
For standard waveforms the
MARKER LIST x
tags are a more compact way to define
markers, but in prinziple this
CONTROL LIST WIDTH4
format can also be used
instead of the
MARKER LIST x
tags.
For multi segment waveforms this
CONTROL LIST WIDTH4
format is required for
marker definition. The binary marker streams of the individual segments are directly
concatenated (without any gap) to one collectively marker stream.
Setting parameters:
Length Defines the number of bytes in the
CONTROL LIST WIDTH4
tag
in ASCII Format and is calculated as follow:
Length = Size of "#" (1 byte) + Number of marker elements m
x
*
(4 bit) / (8 bits/byte)
The value is rounded up for byte alignment.

7.4.2 How to Define Periodically Repeating Traces
If a marker trace is required that marks for example each frame start, it is sufficient to
define the trace ones and repeat it over the length of a waveform. This is useful if you
describe a long waveform and a periodical marker is required.
The following examples use marker traces; control lists are processed in the same
way.
To define periodical marker trace
The waveform in the example on Figure 7-4 consists of 3 frames, each frame is 100-
samples long. The waveform is processed continuously ("Trigger Mode > Auto").
