The CT-1 and CT-2 consist of a current transformer and a flexible probe
cable that attaches between the transformer and the oscilloscope. In
addition, the CT-1 and CT-2 have an internal termination resistor that
reduces reflections that allows the transformer to be disconnected from the
probe cable and left in the circuit. Figure 4 shows a simplified circuit of the
CT-1 and CT-2.
