10.2.2 USB interface
For remote control using USB, the PC and the instrument must be connected over the
USB B interface. Software for instrument control and the VISA program library must be
installed on the controller. VISA detects and configures the Rohde & Schwarz instru-
ment automatically when the USB connection is established. You do not have to install
a separate driver.
You can communicate with the instrument over the USB TMC class or the CDC class
protocols:
●
USBTMC
(USB Test & Measurement Class Specification) is a protocol that is built on top of
USB for communication with USB devices, like GPIB. It defines class code informa-
tion of the instrument, that identifies its functionality to load the respective device
driver. Using VISA library, it supports service request trigger, and other specific
operations, similar to GPIB.
