The oscilloscope is the most frequently used, most flexible device for electric measurements.
It visualizes an electric potential over time function, producing much more information than other potential and current measurement methods.
With an oscilloscope the following quantities can be either directly or indirectly measured:
direct voltage, alternating voltage, direct current, alternating current, time, time delay, phase, phase difference, frequency to view live waveforms, make measurements.

Not giving a perfect square wave. Frequency and time calculation is accurate. When I give 25 Hz 20%duty cycle it does not show on time at 20% instead it shows 50% square wave with clippings. Please give the correct probe ckt diagram for mic input. Thanks for a good scope app in playstore. RK seth.
