Classification: CPC G  H | IPC G  H

Claim 0:
1. A test and measurement device, comprising:
a first input structured to receive a first voltage from a first conductor of a first triaxial cable;
a second input structured to receive a second voltage from a second conductor of the first triaxial cable or a second triaxial cable;
circuitry configured to change modes based on the first voltage and the second voltage;
a power supply configured to receive the first voltage and the second voltage and generate a constant voltage supply based on a voltage differential between the first voltage and the second voltage;
a signal decoder configured to receive the constant voltage supply and monitor the first voltage relative to the second voltage to determine a command code for changing modes; and
an output structured to output a signal.
