3 Welcome to the R&S TS-PSM2
The Rohde & Schwarz multiplex / switch module R&S TS-PSM2 is intended for the use
in the R&S TSVP base units. The module is designed for switching or distribution of
signals of medium power. The R&S TS-PSM2 is controlled by the CAN bus.
The Rohde & Schwarz analog bus can be used to measure voltages and currents on
all circuit nodes. These functions are especially important if current must be measured
for the test object in normal operation and in addition a measurement must be per-
formed in standby mode. In addition to the functionality of a simple power switching
module, small signals can be switched in the lower MHz range with high quality.
Features of the R&S TS-PSM2
●Switching module for power supplies and loads with medium power.
●Switching of voltages up to 120 V
●Switching of currents up to 2 A
●8 relay groups, each with:
– 1 Multiplexer 4:1, two-pin, DPST
or
– 1 change-over contact, one-pin, SPDT with shunt resistor
– 3 make contacts, one-pin, SPST with shunt resistor
– 1 make contact, two-pin, DPDT to local Powerbus/side plug connector
●Indirect current measurement via shunt resistors
●Direct current measurement via R&S analog bus and plug-in module R&S TS-
PSAM (<1 A)
●Self-test of all relays via analog bus and plug-in module R&S TS-PSAM
●Control bus: CAN
Features of the R&S TS-PRIO
●Direct routing out of the local analog bus LABxy of the R&S TS-PSM2 to the con-
nector on the rear panel
●Wiring of the local analog bus LABxy of the R&S TS-PSM2 via relays to the con-
nector on the rear panel
●Automatic detection via SPI

4.2.1 Display elements
There are four LEDs on the rear panel of the R&S TS-PRIO module. The LEDs are
connected to connectors X301 to X304 and can be connected to signals via jumpers.
In the delivery configuration of the jumpers, the associated LED is lit when voltage is
applied to R_AUXn. The brightness depends on the voltage.

5 Installing the module
5.1 Installation R&S TS-PSM2
The R&S TS-PSM2 is a module installed on the front panel of the R&S TSVP base
unit.
1. Install the module as described in the user manuals of the base units.
For additional information about installing the R&S TS-PSM2 and its optional
accessories, see:
●Chapter 5.2, "Installing the R&S TS-PRIO", on page 18
2. WARNING! Risk of electric shock. The test environment, e.g the UUT or additional
power supplies, can supply high voltages to the instruments. In this case, the volt-
age can also apply to the signal output connectors of the R&S TSVP, in particular
the analog bus connector X2.
Therefore, do not connect or disconnect devices from the X2 connectors while con-
nected to an external power supply or UUT.
Always connect both ends of the cable connecting the R&S CompactTSVP and
R&S PowerTSVP. Thus, you avoid the risk of touching the X2 connector with a
possibly hazardous voltage applied.
Take the system into operation as described in the user manuals of the base units.
5.2 Installing the R&S TS-PRIO
The R&S TS-PRIO is a module installed on the rear panel of the base unit.
For a detailed description on how to install modules, refer to the user manual of the
base units.

6 Functions
6.1 R&S TS-PSM2
(see Chapter B, "Block diagrams", on page 38)
6.1.1 Signal concept
The design and construction of the Multiplex/Switch Module R&S TS-PSM2 guarantee
excellent guiding of load and measurement paths. Both „Force“ channels with high cur-
rents as well as „Sense“ channels of voltage and current sources or loads are guided
to the test object via the R&S TS-PSM2. In the opposite direction, test objects can be
switched with single- or multi-pin loads. Eight two-pin 4-to-1 multiplexers make it possi-
ble to select from four measurement signals. These signals can be configured via local
power buses (LPBA and LPBB) to larger multiplexers or can be applied to GND.
Access to the R&S analog bus makes it possible to connect all input channels with
measurement and stimulus modules of the R&S CompactTSVP without the need for
any additional external wiring.
In order to facilitate measurements of high currents without voltage drops interfering,
low-Ohm shunt resisters (22 mΩ) are inserted into each channel. The instantaneous
current can be measured indirectly through these shunt resisters as a voltage value.
All channels are shielded in a low-Ohm design. This reduces voltage drops and cross-
talk.
6.1.2 System functions
The system functions are implemented by a local processor with internal flash.
Communication with the system controller in the R&S CompactTSVP is via the CAN
bus.
The functions of the R&S TS-PSM2 can be summarized as follows:
●Analog function test
●Connection of voltage/current sources
●Connection of test component loads
(original loads, simulated/electronic load)
●Switch simulation
●Power Multiplexer

6.1.3 Flexibility
The structure of the R&S TS-PSM2 in addition to the wide voltage and current range,
combined with effective use extending into the lower MHz range, guarantee a high
level of flexibility and a wide range of uses. Even complex yet flexible load systems
with original loads and/or electronic loads can be implemented using multiple module-
internal connections.
Figure 6-1shows the basic principle with a switching group consisting of four switching
elements. Detail implementation with two changeover contacts offers advantages for
sensed current measurements because the contact resistance of the relay is not intro-
duced as an error. There is no need to take this into consideration in the function.

Figure 6-1: Switching group
This switching group is present eight times on the R&S TS-PSM2 module. Four input
channels each can be switched with two pins to a separate Mux bus. In addition, each
bus can be switched to the local analog bus LABxx (max. 1 A), the local Powerbus
LPBx or the side connector.
Input channels with R&S CompactTSVP measuring system and PXI measuring system
can be connected via the R&S analog bus. The local analog bus is also directed to
connector X20. Signals can also be connected here from the back of the R&S Com-
pactTSVP through corresponding rear I/O modules.
The local Powerbus lines are accessible on side connector X40. In this case standard
PXI modules, which typically do not have a relay multiplexer, can have access to the
multiplexers or the R&S analog bus via flat-band cable on the side. Another application
