Example: How the CONTROL LENGTH tag influences the processing of the
traces
For the example on Figure 4-16 , use the same marker traces and set the
CONTROL
LENGTH
tag, e.g.
{CONTROL LENGTH: 150}
.
Figure 4-17: 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.
4.6.4.7 How to create a control list using tag file format
The R&S SMM100A provides the following ways to create a file containing control sig-
nals:
●
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 134
●
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 175.
●
To use SCPI commands and create a file in binary format, see "To create a data list
in binary format" on page 176.
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.
Using the arbitrary waveform generator (ARB)
