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 the settings that are not currently
active) are reset to the factory values.
Usage: Event
Manual operation: See "Factory Preset" on page 154
7.4 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:ARBitrary: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, a DATA LIST tag or a
EMPTYTAG (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
concerned (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.
R&S AMIQ waveforms can also be loaded on the instrument, where they are converted
internally into an R&S SMBV waveform.
7.4.1 Tag Description
This section first describe the mandatory TYPE tag which identifies the file and is
always located at the start of the file. The rest of the tags used in the R&S SMBV are
