6.1.4 USB Interface
For remote control via the USB connection, the PC and the instrument must be connected
via the USB type B interface. A USB connection requires the VISA library to be installed.
VISA detects and configures the R&S instrument automatically when the USB connection
is established. You do not have to enter an address string or install a separate driver.
USB address
The used USB address string is:
USB::<vendor ID>::<product ID>::<serial number>[::INSTR]
where:
●
<vendor ID> is the vendor ID for Rohde&Schwarz
●
<product ID> is the product ID for the R&S instrument
●
<serial number> is the individual serial number on the rear of the instrument
Example:
USB::0x0AAD::0x006E::100001::INSTR
0x0AAD is the vendor ID for Rohde&Schwarz
0x6E is the product ID for the R&S SMA
100001 is the serial number of the particular instrument
