Abstract
A system includes a surge protection circuit electrically connected via a signal transmission line between a source and an oscilloscope, and including a diode configured to be reverse biased, responsive to a voltage of the source being less than a threshold, to decouple an impedance of the circuit from the transmission line and forward biased, responsive to the voltage being greater than the threshold, to couple the impedance to absorb excess energy of the voltage.
