DESCRIPTION:

The Bird Technologies APM-16 Average Reading RF Wattmeter is a robust, Thruline® style directional RF meter engineered to provide reliable true average power readings across a wide range of frequencies and signal types — from simple continuous-wave (CW) to complex digitally modulated RF used in modern wireless communications (e.g., CDMA, TDMA, FDMA, LTE). 

Using interchangeable APM-series plug-in elements, the APM-16 accommodates a broad spectrum of frequency bands and power levels, allowing technicians to tailor the meter to each application. The meter reads both forward and reflected power directly via its needle display, with clear scales for expanded resolution, making it effective for system tuning, diagnostics, and field verification. 

APM-16’s analog needle movement and element-based architecture make it intuitive for technicians familiar with traditional Bird meters, while its internal circuitry improves average-power accuracy for modern signal formats beyond the capabilities of classic CW-only wattmeters. 

Typical Use Suitability:
Ideal for RF power measurement and diagnostics in communications systems — including cellular, PCS, ESMR, and paging — as well as general analog RF applications where accurate forward and reflected average power readings are required using frequency-matched APM elements.
