General
The
Test System Versatile Platform R&S TS-PWA3
is a standardized modular plat-
form for the program-controlled testing of modules and terminals in the factory or labo-
ratory. With its flexible configuration and the use of worldwide standards, it can be per-
fectly adapted to suit the needs of the user.
The R&S TS-PWA3 is primarily intended as a flexible switching unit for measurement
signals, signal sources and UUT loads. This facilitates the migration of existing and
proprietary "Rack and Stack" systems to a production test platform.
R&S TS-PCA3 and R&S TS-PWA3 can be combined to create more complex ATE
(
A
utomatic
T
est

quipment) systems with a high number of test pins. The R&S TS-
PWA3 is controlled either by the
system controller
of a R&S TS-PCA3 (cPCI system)
or by an external PC. A serial bus system (CAN Bus) is used to trigger the modules in
the R&S TS-PWA3. External cabling is used to make the connection with the measure-
ment and trigger bus of the R&S TS-PCA3.
The R&S TS-PWA3 can be fitted with special ROHDE & SCHWARZ switching and load
modules. The unit provides an analog bus that can be used to make complex connec-
tions. The modules can also be used without any modification in the R&S TS-PCA3.
The peripheral modules can be quickly and flexibly adapted to the UUTs by preceding
the Test System Versatile Platform with an
adapter frame
which connects the signals
securely and with a low rate of wear.

Explanation of Terms
The following terms and standards are used in this manual:
CompactPCI
(abbreviated to “cPCI” in this document) is an open standard of the
PICMG (PCI Industrial Manufacturers Group) that adapts the PCI standard for indus-
trial applications. It uses high-grade connection techniques and mechanical compo-
nents, and applies the same electrical specifications as the PCI standard. This makes
it possible to use inexpensive components and existing PCI developments even under
industrial conditions. Other features include a high integration density, the option of a
19" installation and shielding for the plug-in modules. Its definition as an open standard
means that a large, worldwide variety of cards is available.
This standard is used in the R&S TS-PCA3.
