Types of user data
The user data includes saved instrument settings, data for the different digital stand-
ards, lists for the list mode and the user correction, and the waveforms for the arbitrary
waveform generator.
You can also save the settings in the form of command sequences, e.g. in SCPI or
other languages.
Depending on the content, the user data can be roughly divided into the following
data types:
●
Settings, e.g. the frame setting of the GSM/EDGE standard or the current instru-
ment settings, can be stored and loaded later or in the other instrument path.
See Chapter 10.4, "Saving and Recalling Instrument Settings", on page 628
●
SCPI scripts, a series of commands that can be run to perform a task.
See Chapter 10.6, "Exporting Remote Command Lists", on page 638
●
Externally or internally generated lists, e.g. user correction lists, or data lists can be
loaded in the instrument.
See Chapter 10.7, "Loading, Importing and Exporting Lists", on page 638 and
Chapter 10.5, "Accessing Files with User Data", on page 634
●
Externally or internally generated complex modulation and control data can be loa-
ded in the instrument.
See Chapter 10.5, "Accessing Files with User Data", on page 634
●
Externally generated waveforms can be loaded in the "Arbitrary Waveform Genera-
tion" dialog.
See Chapter 4.7, "Using the Arbitrary Waveform Generator (ARB)", on page 300
Depending on the data storage method, user data can be:
●
Persistent, i.e. user files that are recorded on the data storage.
Data is preserved when instrument is powered off and can be accessed and modi-
fied subsequently.
●
Temporary, i.e. volatile data that the instrument retains while it is powered on.
Volatile data is immediately lost when the R&S SMW is switched off.
File storage location
Without any additional measures, the R&S SMW stores user files on the internal mem-
ory, or if selected, on a memory stick.
Both, the user directory /var/user on the internal memory or the /var/usb direc-
tory, can be used to preserve user-defined data. Any directory structure can be cre-
ated.
The /var/volatile directory serves as a RAM drive and can be used to protect
sensitive information. The data is available temporarily.
Default storage location
The R&S SMW stores user data in the user directory.
