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 current instrument settings, can be saved and loaded later or
used in other instrument of the same kind.
See
Chapter 9.4, "Saving and Recalling Instrument Settings" , on page 480
●
SCPI scripts , a series of commands that can be run to perform a task.
See Chapter 9.6, "Exporting Remote Command Lists" , on page 490
●
Externally or internally generated lists , e.g. user correction lists, or data lists can be
loaded in the instrument.
See
Chapter 9.7, "Loading, Importing and Exporting Lists" , on page 490 and
Chapter 9.5, "Accessing Files with User Data" , on page 486
●
Externally or internally generated complex modulation and control data can be loa-
ded in the instrument.
See
Chapter 9.5, "Accessing Files with User Data" , on page 486
●
Externally generated waveforms can be loaded in the "Arbitrary Waveform Genera-
tion" dialog.
See
Chapter 3.6, "Using the Arbitrary Waveform Generator (ARB)" , on page 145
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 SMBV100B is switched off.
File storage location
Without any additional measures, the R&S SMBV100B stores user files on the internal
memory, the removable memory , or if connected, on a memory stick.
Both, the user directory
/var/user/
on the internal memory or the
/usb/
directory
on the memory stick, can be used to preserve user-defined data. Any directory struc-
ture can be created.
The
/var/volatile
directory serves as a RAM drive and can be used to protect
sensitive information. The data is available temporarily .
If option R&S SMBVB-B80 is installed, the R&S SMBV100B maps the user directory to
the removable memory . If a memory is mounted, user data is saved there. Otherwise
user data is redirected to the volatile memory.
