Average Reading RF Power Meter
The APM-16 RF Wattmeter 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.
Features
- 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
- Interchangeable QC connectors for fast hook-up
