R&S®TS-PSM2Multiplex/Switch ModuleAt a glanceThe R&S®TS-PSM2 is a multiplexer and switching module for medium-power signals and is controlled via a CAN bus. Its innovative technology and versatile wiring capabilities make it ideal for automotive applications.
The special design of the module ensures that lines for differential signals in the audio frequency range are wired with very low interference.
Featuring wide voltage and current ranges and the flexible use of simple switches or complex multiplexers, the mod-ule offers high versatility and expandability. Even complex load systems with real or electronically simulated loads and integrated current measurement capability can be implemented. All channels are shielded and designed with low impedance to keep crosstalk and voltage drops to a minimum.
The R&S®TS-PSM2 multiplex/switch module requires a single slot and can be installed in the R&S®CompactTSVP and R&S®PowerTSVP base units.

Rohde & Schwarz R&S®TS-PSM2 Multiplex/Switch Module 3
Key facts ❙ Medium-power switching module for voltages up to 125 V and currents up to 2 A
❙ Eight independent groups of 3 SPST/1 SPDT relay channels or 4-to-1 DPST relay multiplexers
❙ Relay multiplexers can be cascaded via local power buses
❙ Indirect current measurements on each SPxT channel via shunt resistors
❙ Direct current measurements up to 1 A on all channels via R&S®TSVP analog measurement bus and R&S®TS-PSAM
❙ Connection of CompactPCI/PXI modules via side connector
❙ Selftest of all relays via R&S®TSVP analog measurement bus and R&S®TS-PSAM
❙ Access to R&S®TSVP analog measurement bus via eight bus lines
❙ Control via CAN bus ❙ Use in R&S®CompactTSVP and R&S®PowerTSVP ❙ Device driver for LabWindows/CVI ❙ Generic test software library (GTSL) in DLL format
Flexible signal routingThe module includes eight identical, independent relay groups that can be cascaded via the local power bus to form larger units. Each group contains a double-pole 4-to-1 multiplexer as well as three single-pole make con-tacts and one single-pole make-break changeover contact. The module can thus be used as a switch or a multiplexer, depending on the application.
Low-impedance shunt resistors in each switching channel enable even high currents to be measured without voltage drops. With the relay closed, the resistors enable the actu-al current to be measured indirectly by tapping the voltage via the multiplexer. The relay is designed with two change-over contacts, thus preventing any measurement error due to the resistance of the relay contact.
Each multiplexer bus can also be connected to the local analog bus (LABx), the local power bus (LPBx) or the side connector. The Rohde & Schwarz analog bus allows all channels to be connected to R&S®CompactTSVP measure-ment and stimulus modules; no extra external wiring is required.
The side connector and appropriate wiring enable the R&S®TS-PSM2 to multiplex signals from CompactPCI/PXI modules or to switch them to the Rohde & Schwarz analog bus.

Typical applications ❙ Multiplexing of audio frequency signals ❙ Multiplexing of medium-power voltage and current sources
❙ Switching of DUT loads with optional current measurement
❙ Multiplexing of measurement and stimulus signals of CompactPCI/PXI modules in the system
❙ Switch simulation
Software supportThe R&S®TS-PSM2 multiplex/switch module is supplied with an IVI-compliant LabWindows/CVI driver, which of-fers control panels and online help as common features. Alternatively, all switching functions can be called via the GTSL switch manager.
Selftest and diagnostics for reliable operationThe built-in selftest capability of the module ranges from rapid diagnostics to a fully automatic test of all relays and switching paths (requires R&S®TS-PSAM).
Diagnostic LEDs on the front panel make system inte-gration faster and easier, as the user can see at a glance whether the module is working properly.
