SYMAT 40 is a symmetrical 100 Ω step attenuator. It is switchable between 0 dB, 10 dB, 20 dB, 30 dB, 40 dB and 50 dB.
It’s purpose is to gather properties of the dynamic performance control of PLC/PLT devices. The measurement setup is described in the standard EN 50561-1:2012 chapter 9.2. Figure 4 shows the setup.
