Remote Control via USB Interface

The PC and the instrument must be connected via the USB type B interface. An USB connection
requires the VISA library to be installed. VISA will detect and configure the generator automatically
when the USB connection is established. No entry of an address string and no separate driver
installation is necessary.
The used USB address string is:
USB::<vendor Id>::<product Id>::<serial number>::INSTR
Example:
"USB::0x0AAD::0x0031::100001::INSTR", where:
the first block 0x0AAD is the vendor Id for Rohde&Schwarz,
the second block 0x0031 is the product Id for the R&S AFQ100A
and the third block is the individual serial number on the rear panel of the instrument.
