The factory preset function resets nearly all instrument settings. In addition to the regular
preset by means of the PRESET key, a "Factory Preset" resets also the following values:
●
Reference frequency settings ("Ref Oscillator" menu)
●
Power on settings ("Level/EMF" menu)
●
Network settings including hostname ("Setup" menu)
●
Remote Channel settings including GPIB address ("Setup" menu)
●
Start/Stop Gui Update ("Setup" menu)
●
Display and keyboard settings ("Setup" menu).
To maintain security, password settings and all settings protected by these passwords
like disabled USB and LAN connections are not changed.
Not affected by the "Factory Preset" are also user data, lists or instrument settings files,
created for example by means of the Save/Recall function.
Example: SYST:FPR
all instrument settings (also those that are not currently active) are
reset to the factory values.

7.3 R&S Signal Generator Waveform and List Format
The R&S SMBV uses a tag-oriented format for externally or internally generated wave-
forms as well as for data and control lists. The data can be transmitted via the GPIB
interface from an external computer to the instrument and vice versa.
For these purposes the file is transmitted as a binary data block, using SCPI command
​
[:
​
SOURce<hw>]:
​
BB:
​
ARB:
​
WAVeform:
​
DATA
​
.
A waveform version number is not necessary due to the flexible, tag-based form.
Tags are self-contained information units. Their general format is
{Name: Data}
or
{Name-Length: Data}
. The colon separates the name part and the data part. The
colon can be followed by a space for the sake of legibility.
The
Name
identifies the tag. It is always expressed in capital letters.
The
Data
is tag-specific, and in most cases it is in ASCII plain text.
The
Length
specifies the number of bytes in a
WAVEFORM
tag or
DATA LIST
tag
(from
:
to
}
, ASCII integer).
Each waveform file must begin with the
TYPE
tag. The sequence of the remaining tags
is arbitrary. For each tag an indication shows whether it must be included in the file con-
cerned (mandatory) or may be included (optional).
Unknown tags are not analyzed by the R&S SMBV. On the other hand they are left
unchanged, are saved without an error message and can be read back again.
