Risk of causing instrument unusability
The instrument is equipped with the Linux operating system. Additional software can
therefore be installed on the instrument. The use and installation of additional software
may impair instrument function. Thus, run only programs that Rohde & Schwarz has
tested for compatibility with the instrument software.
The drivers and programs used on the instrument under Linux have been adapted to the
instrument. Existing instrument software must always be modified using only update
software released by Rohde & Schwarz.
The configuration of the operating system is optimally adapted to signal generator func-
tions in the factory. Changes in the system setup are only required when peripherals like
keyboard are installed or if the network configuration does not comply with the default
settings (see chapter 2.6.1, "Connecting the Instrument to the Network", on page 34).
After the R&S SMB is started, the operating system boots and the instrument firmware
is started automatically.
Accessing Operating System
No access to the operating system is required for normal operation.
All necessary system settings can be made in the "Setup" dialog.
The R&S SMB provides an internal flash memory, it does not contain a disk drive. The
flash memory holds the operating system, the firmware and the stored data. Data transfer
is possible via a memory stick connected to a USB interface. The memory stick and the
flash memory are accessed via the "File Manager".
Accessing the File System
The instrument also supports two standard methods to access the file system form a
remote client:
●
FTP (file transfer protocol)
●
File sharing according to the SAMBA/SMB (server message block) protocol.
Both methods allow the access to the folder /var/user/share.
Default password
The FTP and SAMBA/SMB file access use the user "instrument" with the default pass-
word "instrument".
In is highly recommenced that you change this password in the Setup > Security >
Change User Password dialog before connecting the instrument to the network!
