Bird Electronics 4314B Overview

The Bird 4314B Wattmeter is similar to the Bird Model 43 Thruline Wattmeter but also contains electronic circuitry to accurately measure peak envelope power which is present in amplitude modulated signals such as AM broadcast, single sideband and TV video transmitters. The circuitry operates from 2 standard 9V alkaline batteries or an optional A.C. adaptor.
