How does calibrating work?
In the calibration process, Quiver simulates a tiny non-network affecting source of CPD. To distinguish our calibration CPD from other CPD sources we alter the waveform in a particular fashion. In the continual scanning process, Hunter monitors each node for CPD. When Hunter detects CPD with this certain altered characteristic, it knows that this CPD had to come from a calibration signal – and it is recorded as such.
