Overview

The Schwarzbeck SPLIT 100 is a resistive, symmetrical two port splitter with an impedance of 100 ?.

It is part of the measurement setup according to EN 50561-1 which is explained in chapter 9.2. Figure 1 shows the measurement setup with the available components.

The symmetrical splitter SPLIT 100 belongs to a series of measurement equipment for measuring power line communication devices.

This splitter is built in a resistive way. Resistors made with tight tolerances and temperature stable have been used. Thus the device can be used for a wide frequency range.

The SPLIT 100 has a very flat frequency response of typically less than 0.2 dB and can be used up to above 50 MHz. The input and output connectors are symmetrical to earth and show identical properties in each of the three directions.

Splitters like this do have an insertion loss of 6 dB as a matter of principle. They are being used as power dividers (signal distributors) or combiners (to merge signals) also. A 4 dB attenuator is built in at port 3 which results in an attenuation of exactly 10 dB.

This port has to be connected to the switchable, symmetrical attenuator “SYMAT 40”. The total attenuation between AE and EuT results from the sum of the set attenuation of the SYMAT 40 plus the 10 dB insertion loss from port 3 of the SPLIT 100.

If a measurement has to be performed at 20 dB decoupling between AE and EuT for instance, the switch at the SYMAT 40 has to be set to 10 dB.

Safety note

The SPLIT 100 may not be used at the mains directly. Local safety rules for devices connected to mains have to be followed.
