Scientech Technologies Pvt. Ltd. Offers Low Distortion Stable Amplitude Audio Generator, Caddo4036. Scientech Technologies Pvt. Ltd. Is an ISO 9001:2000 certified company. The Low Distortion Stable Amplitude Audio Generator is suitable for modern audio test and measurement technology. It has a frequency range from 10 Hz to 100 KHz and produces a very low distortion sinewave to measure power harmonic distortion and audio preamplifier. It helps in eliminating the need of constant monitoring of voltage level during the frequency response test and provides proper frequency and amplitude setting by a digital Frequency or Amplitude readout. This Audio Generator has been calibrated with two push button attenuators in 20 dB steps, alongwith the 20 dB Vernier which provides a total of -60dB output voltage attenuation.
