Bird APM-16 Wattmeters TDMA CDMA

High Accuracy +/- 1% FS5x More Accurate than Model 43True Average Power - Measures TDMA/CDMA Spread Spectrum

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...
