6.1 Signal concept
The R&S TS-PMB allows the optional connection of measuring instruments to pins on
test products. Connections can be made locally within the module or with other mod-
ules using the R&S analog bus.
The ability to connect measuring instruments to the back of the R&S TSVP avoids
cross-connections at the adapter interface. The unit's extreme compactness makes it
possible to accommodate measuring systems with a number of PXI instruments and a
switch panel with a large number of pins in a single device (one-box solution), making
is particularly suitable for in-circuit testing.
The ground can be connected to the front connector via the ground relay (GND -
GNDNO).
See Chapter B, "Block diagram" , on page 24 for details.
6.2 Scalability
The R&S TS-PMB has two switching matrices (4 x 45). These can also be configured
as 8 buses x 45 pins with external connection or 4 buses x 90 pins, e.g. using plug-in
module R&S
TS-PSAM via the analog bus (see Figure B-2 ).
Three additional instrument inputs (IL1 ... IL3) can be used to connect measuring
instruments at the rear.
The switch panel can be divided into two 4-wire part buses for the parallel test. The
number of pins can be increased with up to 16 modules adding the R&S
PowerTSVP.
6.3 Noise immunity
The signal concept with the analog bus remote from the Compact PCI bus and the trig-
gering via the CAN bus guarantee good signal quality. Despite the unit's compact size,
DC and AC voltages up 120 V (rms) can be connected and passed to other modules.
6.4 Relay matrix
The matrix is designed as a part matrix, i.e. each even I/O channel (e.g. P2) can be
switched to an even part bus (e.g. LABA2) and each odd I/O channel (e.g. P1) can be
switched to an off part bus (e.g. LABA1) (see
