Oscilloscope for iOS is a powerful digital Oscilloscope & Signal Generator application. Designed to plot audio signals, monitor equipment, analyze events, and test circuits, it is also an excellent learning tool. Its GUI includes many standard oscilloscope controls, such as: triggering, time and voltage per division, signal measurement cursors, and more. The app also incorporates a signal (function) generator capable of generating sine, square, triangle, and sawtooth waveforms of up to 22 KHz. Calibration to an external reference signal is supported, guaranteeing the accuracy of measurements.
Input is acquired via the built-in microphone or a probe connected to the headset connector. (When connecting external sources via probes, users must not exceed 1-volt input.) For best results one could use an external accessory such as a dock connector audio input device for the iPhone/iPod touch, or USB audio input such as Griffin iMic for the iPad.
