Abstract
A test and measurement device, including 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; and an output structured to output a signal.
Claims17
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.
