Shock hazard
Before replacing a fuse, make sure that the instrument is switched off and disconnec-
ted from all power supplies.
Always use fuses supplied by Rohde & Schwarz as spare parts, or fuses of the same
type and rating.
2.4 Connecting External Accessories
The equivalent USB ports on the front and/or rear panel of the R&S
SMB can be used
to connect a variety of accessories.
In addition the instrument provides interfaces for network integration (see
"Setting Up a Network (LAN) Connection"
2.4.1 Connecting USB Devices
Via the USB ports, you can connect external devices directly to the R&S
SMB. If you
need more interfaces, you just use an USB hub.
The following list shows various USB devices that can be useful:
●
Memory stick for easy transfer of data to/from a computer (for example 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, for example of the NRPxS(N) Power Sensors 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 con-
tains 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.
