necessary by using USB hubs. Due to the large number of available USB devices, there
is almost no limit to the expansions that are possible with the R&S SMB.
The following list shows various USB devices that can be useful:
●
Memory stick for easy transfer of data to/from a computer (e.g. firmware updates)
●
CD-ROM drives for easy installation of firmware applications
●
Keyboard or mouse to simplify the entry of data, comments, file names, etc.
●
Power sensors, e.g. of the NRP Zxy family
Installing USB devices is easy under Linux, because all USB devices are plug&play. After
a device is connected to the USB interface, the operating system automatically searches
for a suitable device driver.
If Linux does not find a suitable driver, it will prompt you to specify a directory that contains
the driver software. If the driver software is on a CD, connect a USB CD-ROM drive to
the instrument before proceeding.
When a USB device is subsequently disconnected from the R&S SMB, the operating
system immediately detects the change in hardware configuration and deactivates the
corresponding driver.
All USB devices can be connected to or disconnected from the instrument during oper-
ation.
Connecting a memory stick or CD-ROM drive
If installation of a memory stick or CD-ROM drive is successful, the operating system
informs you that the device is ready to use. The device is made available as a new drive
(/usb). The name of the drive is manufacturer-dependent.
Connecting a keyboard
The keyboard is detected automatically when it is connected. The default keyboard layout
is English – US.
Use the "Setup > Keyboard Settings" dialog to configure the keyboard properties.
Connecting a mouse
The mouse is detected automatically when it is connected.
2.5 Linux Operating System
The instrument uses an embedded Linux operating system. To make sure that the instru-
ment software works properly, certain rules must be adhered to concerning the operating
system.
