4314C

4314C, PEP, Single Element, Wattmeter is similar to the 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.

Note:
The 4314C supercedes the 4314B. The new version has the same form, fit and function as the 4314B with the exception of the DC input jack and Power Supply which is not backward compatible but does now include international plug adapters.

Accurate CW and Peak Envelope (PEP) field power measurement over 450 kHz to 2.7 GHz and 100 mW to 10 KW
Uses industry standard Bird elements with space to store 2 additional within the meter housing
Rugged metal housing for the most demanding environments
Quick Change (QC) connectors to minimize the need for adaptors when making critical measurements
