An Oscilloscope (o-scope) are testing devices used in performing output measurement tests and performance verification on various medical equipment. Mostly, these multifaceted devices performs primary measurement of time (e.g. sweep and rise), voltage, peak voltage, peak current, pulse width, and triggering function (i.e. edge, video, pulse and delay) tests. Also, the device performs frequency (in hertzs) testing as well as several additional math function tests. Lastly, technicians can store, print data, or possibly transfer it to an automated computerized maintenance management system for archival.
