Linux Operating System
ATTENTION
Possible impairment of the functioning of the instrument
The instrument is equipped with the Linux operating system. It is thus possible to
install COTS software in the instrument. The use and installation of commercial off-
the-shelf (COTS) software may impair the instrument function. For this reason, we
recommend that you only execute programs tested by Rohde&Schwarz with regard
to their compatibility with the instrument software.
The drivers and programs used in the instrument under Linux have been adapted to
the test instrument. Existing instrument software must only be modified with update
software released by Rohde & Schwarz.
The signal generator is equipped with the Linux operating system (please note statement at the back of
the title page). The configuration of the operating system is optimally adapted to signal generator
functions in the factory. Changes in the system setup are only required when peripherals like keyboard
are installed or in the event that the network configuration does not comply with the default settings (see
sections "Connecting the R&S SMB to a Network (LAN)").
After power-up of the signal generator, the operating system boots and the instrument firmware is
started automatically. The operating system cannot be accessed. All necessary system settings can be
made in the Environment section of the Setup menu.
The R&S SMB provides an internal flash memory, it does not contain a disk drive. The CompactFlash
TM
Card holds the firmware and the stored data. However, data transfer is only possible via a memory stick
connected to a USB interface. The memory stick and the flash memory are accessed via the File
Manager.
Screen saver:
A screen saver is activated by default in the R&S SMB. The display is shut off when no entries via front
panel, external mouse or external keyboard are made for a period of time. The screen saver prolongs
the life time of the display.
The screen saver can be switched off and on and the time period can be set in the Environment
section of the Setup menu.
Connecting an External Keyboard and Mouse
A commercial, external keyboard and mouse with USB interface can be connected to the R&S SMB. A
keyboard simplifies entry of list items, comments, file names, etc. A mouse simplifies control of the
block diagram and of associated menus.
The keyboard and the mouse are connected to a USB interface, type A, on rear panel of the instrument.
The keyboard and mouse are recognized automatically when it is connected. The US keyboard
assignment is the default setting. The keyboard assignment and special settings such as the refresh
rate can be changed in the Environment section of the Setup menu.
