> ======================================================================
> 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.
