VISA library, it supports service request, triggers and other operations that are com-
monly found in GPIB devices.
Besides USBTMC, the NRP legacy protocol is available to ensure the compatibility of
the R&S NRPxxT(N) power sensors with the R&S
NRP
‑
Z series of power sensors. The
usage of this protocol is not recommended for new applications.
The resource string represents an addressing scheme that is used to establish a com-
munication session with the sensor. It is based on the sensor address and some instru-
ment- and vendor-specific information.
USB Resource String
The syntax of the used USB resource string is:
USB::<vendor ID>::<product ID>::<serial number>[::INSTR]
where:
●
<vendor ID> is the vendor ID for Rohde & Schwarz (0x0AAD)
●
<product ID> is the product ID for the Rohde & Schwarz sensor
●
<serial number> is the individual serial number on the rear of the sensor
