ABSTRACT:
Electronic signal measurement apparatus for the acquisition and display of short-duration analog signal events, in the form of a hand-held instrument which includes maximum and minimum signal value detection circuits for capturing the extremes of a rapidly changing analog signal. The captured values are then digitized by an analog-to-digital converter to generate data which can be stored and subsequently displayed in the form of a histogram evidencing the occurrence or lack of occurrence of a particular type of signal event.
