APM-16, Average Reading Power Meter
APM-16

APM-16, Average Reading Power Meter 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
