Oscilloscope

Equipment
A test instrument that captures and displays electrical waveforms as voltage over time. In PEMF device testing, an oscilloscope measures the voltage waveform across the coil or a sense resistor during a pulse. From that waveform, rise time, fall time, pulse width, duty cycle, frequency, and waveform shape are derived.

Callouts mark the rise time and fall time of the edges, the pulse width at half height, one full cycle from which frequency and duty cycle follow, and the flat top naming the waveform shape.One cycle: frequency, duty cycleWaveform shape (square)Pulse widthRise timeFall timeVolts/divTime/divTime →© 2026 Gauss Labs
A simulated oscilloscope screen. The scope captures the coil's voltage pulse as a trace over time, and the report derives its timing numbers from that trace: the rise time and fall time of the edges, the pulse width at half height, one full cycle setting the frequency and duty cycle, and the waveform shape read from the form of the trace.
