R&S
TS-PMB
5 Function Description
5.1 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 TSVP avoids cross-
connections at the adapter interface. The unit's extreme compactness makes it possi-
ble 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).
5.2 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 TS-PSAM via the analog bus (see
Three additional instrument inputs (IL1 ... IL3) can be used to connect measuring
instruments at the rear. Up to12 modules can be used in the CompactTSVP.
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 PowerTSVP.
5.3 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 125 V (rms) can be connected and passed to other modules.
5.4 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
This does not apply to channels IL1 ... IL3, which can be switched to all lines of the
local analog bus.
