The APM-16 is designed to keep pace with the ever growing complexity of digitally-based communication systems. Bird's model 43 and most other wattmeters available today were designed to measure power of constant amplitude, sinusoidal waveforms.
Designed especially for RF power measurement in PCS, cellular, ESMR, paging and similar communication systems
Equally effective for measuring RF power in conventional analog systems
Uses APM-series plug-in elements to cover a wide range of frequency and power levels. Simple Thruline® style operation for instant forward or reflected power readings
