14.1 Remote control interfaces and protocols
For remote control, communication between the R&S NRX and the controlling host is
established based on the following interfaces and protocols.

*) VISA is a standardized software interface library providing input and output functions to
communicate with instruments. A VISA installation on the controller is a prerequisite for
remote control over LAN (when using VXI-11 or HiSLIP protocol) and USBTMC interfaces.
See also Chapter 14.1.2.1, "VISA resource strings" , on page 466.

Computer requirements
●
VISA library
A USB connection requires the VISA library to be installed. VISA detects and con-
figures the R&S NRX automatically when the USB connection is established.
