The desktop analyzer in action - generator, oscilloscope, FFT and frequency response.

Phonalyser multifunction view — Multifunction view. Signal generator, oscilloscope and FFT analyzer side by side - the everyday measurement layout.

Ultra-low-distortion FFT — Ultra-low-distortion FFT. Sub-ppm THD pulled out with coherent averaging, measured through a tuned twin-T notch and DAC pre-distortion.

Generator and FFT — Generator + FFT. The signal generator driving the FFT analyzer - per-harmonic readout, windows and coherent averaging.

Generator and oscilloscope — Generator + oscilloscope. The triggered time-domain view with V_pp/V_rms/period/frequency statistics.

Frequency response measurement — Frequency response. Logarithmic-sweep deconvolution - magnitude and phase across the whole band in seconds.

Frequency response with overlay — Frequency response - compare / calibrate. Overlay against a reference curve or a saved .frc calibration.

Want to try it yourself? Run the analyzer in Chrome, Edge or another Chromium-based browser - no install - with the web version, or grab a native build.
