Sweep Tone / Chirp Tone Generator

Introduction

Sweep tones are often used for frequency response analysis in association with a spectrum analyser, or by ear when detecting resonances.

Our sweep generator works from 0 Hz (DC) up to 24 kHz (in 48 kHz mode) and offers both linear and logarithmic time scales.

When analyzing the sweep by ear, audible markers can be added for your convenience. When markers are enabled, short pulses will be sent every 10 Hz (up to 90 Hz), 100 Hz (from 100 Hz to 900 Hz) and 1000 Hz (from 1000 Hz and upwards). By counting the pulses, you will easily find out the frequency currently playing when a resonance occurs.

Tone duration can be as short as 10ms (0.01s). In such a case, the continuous sweep degenerates into a short "burst" of sound, often referred as a chirp.
