    High Accuracy +/- 1% FS
    5x More Accurate than Model 43
    True Average Power - Measures TDMA/CDMA Spread Spectrum

    True Average Power Reading Wattmeter
    The APM-16 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.

    • 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
    • APM-16 accuracy is +/- 1% FS and +/- 4% reading

    Much improved accuracy over the Model 43 type meters.
    Requires APM-16 elements. Elements are sold separately.
