Example: How the CONTROL LENGTH tag influences the processing of the
traces
For the example on Figure 5-20, use the same marker traces and set the CONTROL
LENGTH tag, e.g. {CONTROL LENGTH: 150}.
Figure 5-21: Example: Processing of control signals if the CONTROL LENGTH tag is used
The length of all control signals is determined by the CONTROL LENGTH. Observe how
the marker traces are processed. In this example, both marker traces are repeated
each 150 samples.
5.7.4.7 How to Create a Control List Using Tag File Format
The R&S SMW provides the following ways to create a file containing control signals:
●
to use the dedicated "Control Data Editor" and create a file in ASCII format and
with extension *.dm_iqc, see "To create a control list in ASCII format manually"
on page 286
●
To use the tag-oriented format and create a data list file, see "To create a data list
file using tag file format" on page 326.
●
To use SCPI commands and create a file in binary format, see "To create a data list
in binary format" on page 326.
To create a control list using tag file format
To create an ASCII control list file directly, use the provided tag commands.
1. Use a hex data editor and create the mandatory tags:
●
TYPE
●
[TRACE] LIST
The [TRACE] LIST tag defines the individual markers or control traces in a com-
bined {Pos:State} way within the control list period (CONTROL LENGTH).
2. Use a hex data editor and create the recommended tag CONTROL LENGTH.
This tag defines the periodicity of the total control list
3. Add the required optional tags.
They can be inserted after the TYPE tag in arbitrary order.
An example of the control list file contents could be:
Using the Arbitrary Waveform Generator (ARB)
