R&S®TS-PSM1Power Switching ModuleAt a glanceThe R&S®TS-PSM1 is a power switching module controlled by a CAN-bus interface. Its innovative technology and versatile functionality make it ideal for automotive and high-current switching applications, e.g. power-management and test-load paradigms.

The special design of the module ensures ideal routing of supply and load paths through the test system. High-current force channels and sense channels from voltage or current sources can be switched and routed to the DUTs via the module. In the opposite direction, single-pole or multipole loads can be applied to the DUTs. High-power multiplexers on the module make it possible to select different load simulations for integration in the R&S®TSVP test system versatile platform base units.

The currents and voltages can be measured or monitored at all switching nodes by means of additional relays on the module and the Rohde & Schwarz analog bus. Shunt resis-tors are inte grated for measuring high currents.

This characteristic is particularly important if the power consumption of the DUT must be measured during nor-mal operation and in standby modes. Additionally, the tests of various operating modes and their current con-sumption can be executed without interrupting the DUT’s powerpath.

The R&S®TS PSM1 power switching module can be used in the R&S®CompactTSVP and in the R&S®PowerTSVP. It is a CAN-bus- controlled module which takes up only one slot.

Rohde & Schwarz R&S®TS-PSM1 Power Switching Module 3

Key facts ❙ Power switching module for supplies and loads ❙ Switching module for voltages of up to 70 V ❙ 8 high-power channels with 16 A max. ❙ 10 power channels with 2 A max. ❙ 4 high-power 4-to-1 multiplexer channels with 16 A max. ❙ Indirect high-current measurements on high-power channels via shunt resistors

❙ Direct current measurements up to 1 A in all channels via R&S®TSVP analog measurement bus and R&S®TS-PSAM

❙ Selftest of all relays via R&S®TSVP analog measurement bus and R&S®TS-PSAM

❙ Analog measurement bus access to 8 bus lines ❙ Control interface based on CAN bus ❙ Usable in R&S®CompactTSVP and R&S®PowerTSVP ❙ LabWindows/CVI device driver support ❙ GTSL test software library in DLL format

Flexible signal routingThe design of the switching module and the large voltage and current ranges ensure high flexibility and a wide ap-plication range.

Device-internal connection of the multiplexed power chan-nels even makes it possible to configure complex yet flex-ible load systems with original or electronic loads to obtain a high- current R&S®PowerTSVP switching instrument.

When lower power signals are measured, the signal con-cept relies on the system-wide analog bus.

Soft front panel for the R&S®TS-PSM1.

Proper handling of analog signals led to the R&S®TSVP analog bus interconnection solution. The analog bus is lo-cated immediately above the front connector area, where space is provided for on-board signal conditioning and sig-nal routing. The distance to the digital signals on the back-plane significantly improves signal quality.

In addition, dedicated switching modules such as the R&S®TS-PSM1 are controlled via the low-noise and inter-ference-resistant CAN bus, which ensures overall high reli-ability and signal quality, especially in the vicinity of high-current signals.

Direct current measurement via the analog measurement bus is limited to 1 A, but measurements up to 16 A can be performed by forwarding the shunt resistor voltages of the R&S®TS-PSM1 via the analog bus to a precise multimeter such as the R&S®TS-PSAM in the R&S® CompactTSVP.

Typical applications ❙ Switching of voltage or current sources to DUTs ❙ Switching of DUT loads as original loads or simulated/electronic loads

❙ Power multiplexer for DUT signals to test devices ❙ Analog functional test for general-purpose signals ❙ Switch simulation for DUTs

Software supportA LabWindows/CVI driver according to the IVI standard is available for the module’s switching functions. Function panels and online help are available as common features for the LabWindows/CVI driver.

Security by selftest and diagnostic featuresThe module’s built-in selftest capability ranges from fast diagnostics to the complete, automated evaluation of all relays and switching paths (R&S®TS-PSAM required). Di-agnostic LEDs on the module front panel speed up system integration and allow proper operation to be determined at a glance.
