PXI
(PCI eXtensions for Instrumentation) is a standard defined by National Instruments
which extends cPCI. The
Test System Versatile Platform
adopts the same mechani-
cal specifications and the interfacing with the trigger system.
CAN
(Controller Area Network) is a serial bus system whose high system and configu-
ration flexibility is achieved by a content-oriented addressing scheme, i.e. it defines so-
called “message identifiers“ and not device addresses. Systems can be added to an
existing network without the need for hardware or software modifications. The CAN
protocol is defined in ISO 11898.
Rear I/O
is the name given to a design that allows input and output lines of the cPCI
connectors P1 and P2 to be accessed from the rear of a backplane. Pluggable Rear
I/O modules can be used for this purpose in the R&S TS-PWA3 and the R&S TS-
PCA3.

System Information
The R&S TS-PWA3 has a modular structure that allows a range of system configura-
tions tailored to the specific needs of the user.
The R&S TS-PWA3 contains 16 slots for front plug-in modules conforming to Rohde &
Schwarz format. The connector P2 that is defined in the cPCI standard is referred to
here as P20, because of a different assignment. Slots A3, A4 are fitted with a PSU as
standard. An optional R&S TS-PCPA power pack or the optional R&S TS-PXB2 back-
plane extension can be plugged into slots A1 and A2. Slots 1 to 16 provide access to
the PXI trigger bus, CAN bus and analog bus. If an optional R&S TS-PXB2 is used, the
CAN bus is also available at slots A1 and A2. Space for Rear I/O modules is provided
at the back of the R&S TS-PWA3.
