Signal Generator SG-2400

A precision signal generator in your pocket. Six waveforms, 10 Hz – 20 kHz, anti-aliased synthesis, and a hands-on retro interface.

SignalGenerator SG-2400 is a precision audio signal generator built for musicians, audio engineers, and anyone who needs clean, accurate test tones.

WAVEFORMS • Sine — pure fundamental tone • Square — band-limited with anti-aliasing • Sawtooth — band-limited with anti-aliasing • Triangle — band-limited via integrated square wave • White noise — flat frequency spectrum • Pink noise — equal energy per octave

FREQUENCY RANGE 10 Hz to 20 kHz with configurable step increments (0.1, 1, 10, 100 Hz). Dial in frequencies with the rotary jogwheel or tap the display to type an exact value.

AUDIO ENGINE Direct sample-level synthesis at 48 kHz with no intermediate buffers. Anti-aliasing eliminates artifacts on square, sawtooth, and triangle waves at high frequencies.

INTERFACE Inspired by classic test equipment and old school handheld electronics. Real-time waveform display, musical note detection with cents offset, and a tactile jogwheel with step-scaled sensitivity.

HEARING SAFETY Always start at a low volume. Use caution with headphones.
