A small audio test generator is very useful for quickly tracing a signal through an audio unit. Its main purpose is speed rather than refinement. A single sine-wave signal of about 1 kHz is normally ...

Leading life-safety equipment manufacturer, C-TEC, has launched an innovative new Audio Signal Generator for testing induction loop amplifiers. Specifically designed to simplify the testing of ...

This all-analog circuit provides three key waveforms simultaneously and at the same frequency within the audio band. It is useful for evaluating audio systems, transformers, cables, and other ...

It’s been a while since the last installment in our Know Audio series, in which we investigated distortion as it applies to ...

This audio frequency generator is a triggered signal generator. When a positive pulse of about 6 volts (minimum) is fed to the circuits input , a modulated audio signal comes out of the output. The ...

Designed for audio product testing, the VP-8192A, -8193A and -8194A AM/FM signal generators feature a bandwidth from 100 kHz to 140 MHz and a 0.1 dB electronic attenuator with up to 126 dBµV output.

The Eico model 377 was a pretty common audio signal generator. [The Radio Mechanic] picked one up from 1956 that was in reasonably good shape, and shares a teardown and repair of the unit that you can ...
