4.4.1 Connecting USB Devices
The USB interfaces on the front and rear panels allow you to connect USB devi-
ces directly to the instrument. The number of USB connectors can be increased
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 RTO.
The following USB devices can be useful, for example:
●USB flash drives to save screenshots and measurement results, and for easy
installation of firmware applications
●Keyboard and/or mouse to simplify the operation and the entry of data, com-
ments, filenames, etc.
●Printer to print measurement results and screenshots
You can connect or disconnect all USB devices during operation of the instru-
ment.
Installing USB devices on R&S RTO is easy under the Windows operating sys-
tem, because all USB devices are plug&play. After a device is connected to the
USB interface, Windows automatically searches for a suitable device driver.
If the operating system does not find a suitable driver, it prompts you to specify a
directory that contains the driver software. If the driver software is on a storage
media, connect the appropriate drive to the instrument before proceeding. If the
instrument is integrated in a network, you can also install driver data stored in a
network directory.
When a USB device is disconnected from the R&S RTO, Windows immediately
detects the change in hardware configuration and deactivates the corresponding
driver.
The properties of external USB devices are configured in the operating system,
not in the R&S RTO software. It is recommended that you use mouse and key-
board to access and modify the settings of the Windows operating system. To
access Windows, press the Windows key on the external keyboard, or select
"File" > "Minimize Application" on the R&S RTO menu.
