Abstract:
1. An oscilloscope current probe system, comprising a first probe head, a second probe head, a probe amplifier unit and a probe head identifier, in which: the first probe head and the second probe head are interchangeably connectable to the probe amplifier unit; each of the first probe head and the second probe head comprises a respective electrically-readable type identifier, a respective current input to receive a current to be measured, a respective internal sensing resistor in connected series with the current input, and a respective output at which a measurement voltage across the sensing resistor is output; the first probe head has a sensing resistor resistance different from, and a type identifier that reads differently from, the sensing resistor resistance and the type identifier, respectively, of the second probe head; the probe amplifier unit comprises a differential amplifier to amplify the measurement voltage output by the one of the probe heads; and the probe head identifier is to read the type identifier of the one of the probe heads connected to the probe amplifier unit.
