5.1.3 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.
shows 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 5-1: 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
