  • Audio Signal Generator

    CRY5520 - CRYSOUND

    CRY5520 Audio signal generator uses SCM for sweep control and the digital-analog mode and performs stably. With very low distortion, sine wave output, good stability, and frequency range for the entire audio frequency domain, it is especially suitable for the pure tone test of speakers and headphones. It can work in both logarithmic sweep and manual frequency modulation modes. The sweep start point, end point and sweep time can be set randomly. Manual frequency modulation is divided into rough modulation and fine modulation, which can quickly and accurately modulate frequency. It adopts 128 × 64 dot matrix LCD and simultaneously displays frequency and voltage values with synchronous output.
