Electonic Test Equipment - Wave Oscillator

Overview

The All Wave Oscillator [mains powered] manufactured by AVO Ltd, London is an accurate modulated oscillator suitable for all radio service and general laboratory work.

Historical information

The AVO (Amps, Volts and Ohms) Meter Model 7 was introduced into service in 1936. It was an improved version of the original AVO Multimeter, which was first developed in 1923. The design concept was the work of Post Office engineer Donald Macadie, who at the time of the introduction of the original AVO meter was a senior officer in the Post Office Factories Department in London and although the original model was a DC only instrument, many of its original features remained unaltered.

AVO No 7 multimeters were renowned for their reliability, robustness and simplicity of use. The incorporation of a mechanically operated cut out linked to the meter movement and the two switch range selection system endeared these meters to generations of Signals technicians

Inscriptions and markings

An electronic oscillator is an electronic circuit that produces a periodic, oscillating or alternating current (AC) signal, usually a sine wave, square wave or a triangle wave,[1][2][3] powered by a direct current (DC) source. Oscillators are found in many electronic devices, such as radio receivers, television sets, radio and television broadcast transmitters, computers, computer peripherals, cellphones, radar, and many other devices.
