Preparing for Use > Linux Operating System
Linux Operating System

The instrument uses an embedded Linux operating system. To make sure that the instrument software works properly, certain rules must be adhered to concerning the operating system.

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 functions 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 "Connecting the Instrument to the Network"). After the R&S SMC 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 SMC 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 password "instrument".

It is highly recommenced that you change this password in the "Security" dialog before connecting the instrument to the network!

Refer also to Application Note 1GP72 "Connectivity of Signal Generators", provided on the Rohde & Schwarz website, at http://www.rohde-schwarz.com/appnotes.

Screen saver

A screen saver can be activated in the R&S SMC. When active, 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.

Use the "Setup > Display Settings" dialog to switch on or off the screen saver and to adjust the screen saver settings.
