Commentary
Low distortion generator kit of measuring instrument series.
The M-5GL was developed mainly for measuring the distortion rate of audio amplifiers. For this purpose, the oscillation frequency is set at 3 points of 100 Hz, 1 kHz and 10 kHz, which are often used for measuring the distortion rate, and an ultra-low distortion rate of the level required for measuring audio amplifiers is achieved.
A quadrature circuit using a state variable filter is used for the oscillation circuit to realize an oscillation waveform with an ultra-low distortion factor.
Uses a high-performance, low-noise OP amplifier.
It uses an attenuator with 600 Ω constant output impedance that can be changed in conjunction with 10 dB steps.
Equipped with oscillation frequency fine adjustment function.
