This app is a combination of oscilloscope, spectrum analyzer and AM/FM synthesizer and works in the audio ranges from 0 ... 22 kHz using the integrated audio interfaces. The three operating modes offer a wide range of functions and settings. Oscilloscope • Very fast image display and real-time triggering • Trigger modes: automatic, normal, single-shot Trigger edges: rising, falling, both • Automatic measurement of frequency, period and amplitude • Manual measurement of frequency, period and amplitude • Freely selectable trigger level and time • Variable zoom and offset Spectrum Analyzer • Very fast image display with the help of Apple Metal graphics acceleration • Logarithmic or linear frequency axis • Display modes: spectrum, waterfall and combined • Automatic determination of the dominant frequency • Music note calculation of the dominant frequency • Possibility to transfer the dominant frequency to the generator/synthesizer • Cursor for manual frequency determination • Adjustability of bandwidth, FFT window and high-pass filter • Adjustability of color scheme, brightness and contrast of the waterfall display Synthesizer • Waveform synthesis in real time • AM and FM modulation • Different waveforms for base signal, AM and FM modulator • Multiple memory locations for quick switching between different settings • Direct input of all numerical parameters
