THRULINE Directional Wattmeter and Plug-In Elements for
Analog and Digitally-Modulated RF Signals

APM16

Bird developed the APM-16 for engineers and technicians who work with today™s increasingly common digital RF technologies, where accurate average power measurement with conventional CW-type wattmeters can be difficult and uncertain.

Read forward or reflected power instantly and accurately, regardless of waveform, by simply rotating the element.

The shock-mounted meter features a linear scale with mirror band to improve reading accuracy. Interchangeable QC connectors add to the APM-16™s versatility.

  • Accurately measures analog and complex digital RF signals.
  • Designed for CDMA, TDMA, FDMA, COFDM, and multi-carrier transmission systems.
  • Can be used for pre- or post-combiner power measurements.
  • Ruggedly constructed for demanding field use.

The APM-16 can accurately measure the output power of multi-carrier systems.


1W–1000W and 400MHz–2.3GHz for Cellular, PCS, and Other Wireless applications

APM Plug-in Elements
APM Plugin
This subset of available APM-16 elements covers 400-2300 MHz. Other elements extend the measurement range down to 2 MHz, making the APM-16 ideal as a high-accuracy, general-purpose HF wattmeter.

  • Customize the APM-16 to precisely match power and frequency  requirements.
