Method for Measuring the Phase Spectrum of the Output of a Frequency Source Used in the Calibration of an Electroshock Weapon Characterization System.

Electroshock weapons (ESWs) output a transient burst of impulse-like high-voltage electrical signals that can incapacitate a human target. To ensure safe and effective operation of ESW, their outputs must be accurately measured. Accordingly, the systems used to measure the output of an ESW must be accurately characterized, and their response functions must be known for subsequent processing of the ESW output waveforms (current and high voltage). The long epochs (> 5 s) and high-bandwidth frequency content (> 200 MHz) of the ESW output require unique measurement instrumentation and calibration tools. A frequency-domain swept-frequency method is proposed here for the calibration of the phase response of an ESW measurement system. This method, although motivated by the ESW measurement application, is also applicable to other systems.
