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.
Modern wireless communication systems can use a variety of digital techniques to combine many voice data channels into a complex, composite RF signal. Measurement of such signals with a conventional wattmeter may yield unacceptable errors. The APM-16 employs active circuitry to deliver accuracy of ± 5% for multiple-access technologies such as CDMA, TDMA, FDMA and other digitally-encoded communication systems.
Frequency Range: 2 MHz - 2.3 GHz
Power Range: 1-1000 Watts
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
