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.
