Audio Sweep Generator

Features:

Base on novel RC oscillated technique, tiny sine distortion, especially suitable for speaker and MIC testing.

Frequency display, output amplitude digital display, readout more accurately, less error.

Beginning and starting point can be arbitrated adjusted.

Large power supply, max. to 150W.
