- APM-16 射頻功率表|BIRD|射頻功率計|鳥牌|功率計 品牌: 美國鳥牌(BIRD) Average-Reading Portable Wattmeter 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 聯系人：姚小姐：電話13510169620 QQ:1946418560 廖先生13590256385 QQ：785298834 The Model APM-16 RF wattmeter is designed to keep pace with the ever growing complexity of digitally-based communication systems. Bird's Model 43 and most other wattcmeters 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
