Remote control interfaces and protocols
For remote control, communication between the R&S NRP series power sensor
power sensors and the controlling host is established based on various interfaces
and protocols.
Depending on the power sensor type, the power sensors support different interfa-
ces for remote control.
●
R&S NRP USB power sensors are always accessed using USB.
●
R&S NRP LAN power sensors can be accessed using USB or Ethernet.

) 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 USBTMC and LAN (when using VXI-11 or HiSLIP protocol) interfaces.

USB interface
For remote control using USB connection, the computer and the power sensors
must be connected via the USB interface. A USB connection requires the VISA
library to be installed. VISA detects and configures the R&S
power sensors auto-
