Confirming Characteristics

The various characteristics of common mode choke coils can be displayed in graphs.
  

Impedance, ESR, reactance (common to common mode / differential mode), transmission characteristics (S21, etc.) and reflection characteristics (S11, etc.) of single-end, and transmission characteristics (Sdd21, etc.) and reflection characteristics (Sdd11, etc.) of mixed mode

In the graph, the characteristics can be compared easily, because the characteristics of multiple items can be overwritten.


* In the XY axis of the graph, the Linear/Log can be switched and the display range can be set.
