PXI
(PCI eXtensions for Instrumentation) is a standard defined by National Instruments
which expands the CompactPCI, using its mechanical specifications and the connec-
tion with the system controller. The PXI standard is fully compatible and also defines a
number of additional signals which are useful for measuring applications, such as the
PXI Triggerbus.
PCI-PCI bridges
are used to connect a number of cPCI or PXI segments, thereby
increasing the number of peripheral slots in cPCI or PXI systems.
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-PCA3 and the R&S TS-
PWA3.

System Information
The R&S TS-PCA3 has a modular structure that allows a range of system configura-
tions tailored to the specific needs of the user.
Up to 13 cPCI/PXI modules can be fitted in addition to the system controller (slot 1). A
further slot (slot 16) is provided for special R&S plug-in modules (without J1 connec-
tor). 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 backplane extension can be plugged into slots A1
and A2. Slots 1 to 16 provide access to the analog bus. The CAN bus is available at
slots 5 to 16 (starting with backplane version V4.x in slots 3 and 4 as well). If an
optional R&S TS-PXB2 is used, the CAN bus is also available at slots A1 and A2.
There is space for rear I/O modules in the rear section of the R&S TS-PCA3.
The configuration of the R&S TS-PCA3 is shown in
