RK1312-20 Audio Sweep Signal Generator, integrating high-precision voltage controlled sine wave oscillator, logarithmic sweep frequency generator, low distortion audio power amplifier, 3 three-quarters LCD voltage and frequency display, can be widely used in acoustics, vibration, and electronics
As a signal excitation source in the field of communication, it is particularly suitable for pure tone listening of speaker units and speaker systems (speakers).
The instrument adopts an RC phase-shift voltage controlled oscillator, which produces sine waves with good adjustability, wide range, high frequency and amplitude stability, and pure waveform; It can be manually frequency adjusted or scanned with logarithmic frequency. The starting and ending points, as well as the scanning time, can be set as needed; built-in
The power amplifier has low distortion, low load adjustment rate, and flat amplitude frequency response. The accompanying attenuated output signal (load impedance greater than 600 Ω) can be directly applied to the input end of the amplifier, providing a signal source for the detection of active audio systems.
This instrument provides multiple protection functions: power on/off delay output, current limiting protection, and ultra strong short-circuit protection, which further improves reliability and provides users with more convenience and protection.
