6.1 Applications of Module R&S OSP-B103
Figure 6-1: R&S OSP-B103
The R&S OSP-B103 Digital I/O Module with 16 input/output ports can be used to con-
nect additional relays to the R&S OSP.
The following application supports EMI systems in measuring radiated spurious emis-
sions of mobile phones and other equipment. These EMI systems need a series of
notch filters to be switched during the measurement. Depending on the system design
and due to the size of the notch filters, the relays are mounted close to the notch filters
to keep the cable loss low. The module R&S
OSP-B103 can be used to control these
“remote relays” via the R&S OSP. The following chapter gives an example for such a
solution.
The following example is shown for a maximum configuration. Check the R&S OSP-
B103 version for maximum output current.

6.1.1 Controlling External Relays with R&S OSP-B103
The module R&S OSP-B103 has 16 output lines and 28 V DC power supply. The out-
put lines are open-drain type and are switched to ground when activated.
The following table gives a short specification and recommendation of the preferred
relay type to be used with the R&S
OSP-B103.
