5. Characteristics of Target Interface
The target interface behaves as if the actual device is connected in terms of functionality. However, in terms of
characteristics, the behavior of the target interface sometimes differs from the behavior when the actual device is
connected. Figure 5-1 shows an equivalent circuit of this product.
