ONYX Apps (www.onyx3.com) has unveiled Oscilloscope 1.0 for iOS, the company’s low cost Oscilloscope and Signal Generator app designed to monitor equipment, test circuits, analyze events and plot audio signals. The oscilloscope is also an excellent learning tool. Input signals can be acquired through an external device or built in microphone connected to the microphone input. GUI includes several standard oscilloscope controls like signal measurement cursors, triggering, voltage and time per division, and more. The new app also incorporates a signal generator capable of generating square, triangle, sine, and sawtooth waveforms (up to 22KHz).
Most of the existing iPhone/iPad and PC oscilloscopes gather data through the sound card’s audio input. This results in a major limitation compared to a real scope – since a normal audio input employs a 48KHz sampling rate, these applications can only analyze signals between 20Hz and 20KHz. Despite the limitation, the oscilloscope is perfect for analyzing audio, learning oscilloscope measurement basics or measuring low frequency signals.
Oscilloscope 1.0 features real-time waveform display (60FPS), retina display support, set trigger level and pre-trigger time, triggering modes (auto, normal, and single), built-in function generator, reference signal calibration, measure signal data using cursors, pause function to get a screen capture, double tap screen to use Black Panel mode, “finger pinch” on screen to set time and voltage base, and four color themes to choose from.
“Though its frequency range is somewhat limited, Oscilloscope 1.0 is an extremely affordable, digital oscilloscope and signal generator,” said Eugene Klein, company CEO. “It’s a great way to learn the basics of signals measurement before investing a lot in a dedicated test device.”
