2.2 Board description
The R&S RT-ZF4 10Base-Te fixture replaces the "Twisted Pair Model" section of
the R&S RT-ZF2 Ethernet test fixture when performing 10Base-Te compliance
tests because the twisted-pair models of 10BASE-T and 10BASE-Te are different.
S201
Switches between resistive and inductive load.
S202
Switches between two different inductive loads. Set S201 to inductive load to use
the effect of S202.
