我国政府在 1993 年制定的金卡工程实施计划,是一个旨在加速推动我国国民经济信息化进程的重大*工程,由此各种自动识别技术的发展及应用十分迅猛。现在, RFID 技术作为一种新兴的自动识别技术,也将在中国很快地普及。
国家发改委高新技术司副司长綦成元表示,可以预见, RFID 技术在未来几年内将达到数百亿美元的市场规模,不仅如此, RFID 的应用还将给留守、物流等产业带来革命性的变化。遗憾的是, RFID 技术在中国却一直未能广泛普及,其主要原因在于缺乏一套可供业界共用的标准,尤其是中国的 RFID 标准尚未正式确立。尽管如此,中国 RFID 市场还是在悄然增长, IDC 数据显示, 2005 年整个 RFID 在中国的市场容量为 4.7 亿元,到 2009 年就会膨胀到 58.7 亿元,其年复合增长率大约是 65.6% 。

对于标签zui主要的指标包括:频率响应以及品质因素 Q
a. 对于这种带引线电磁耦合式的标签可以使用 4294A 阻抗分析仪配合 16047E 测试夹具进行阻抗的测试,通过谐振频率点可以得出该标签的工作频率。
b. 如果标签没有引线,那么可以使用 4294A+42941A 的探针来进行接触式的阻抗测试,同样可以得到其谐振频率。
c. 对于高频 (HF) 、超高频 (UHF) 或微波的 RFID 标签(射频卡)测试,可以采用 E4991A 射频阻抗分析仪或 ENA ( E5071B )网络分析仪进行测量。
滚球体育d. 通常,对于已经封装好的标签测试,由于没有接触点,可以利用环路天线可以进行非接触测量。

读写器射频模块的主要功能为:
a. 产生信号并且发射,激活标签并为其提供能量;
b. 对发射信号进行调制,用于将数据传输给标签;
滚球体育c. 接收并解调来自标签的射频信号。

对于读写器的测量,主要包括:
a. 输出功率测试
读写器的输出功率直接影响到识别距离。对于输出功率的测试可以使用功率计 E4416A+E9300A 来完成。
b. 频谱以及解调分析测试
一般 RFID 系统都采用 ASK 或者 FSK 调制,因此可以使用 E443xC 系列 ESG 产生调制激励信号,采用 ESA 系列频谱分析仪或 MSO6000 系列示波器以及 89601A 矢量信号分析软件来进行解调分析。
c. 天线匹配测试
采用 E5071B ENA 或 4396B 进行天线匹配,方向性等参数测试。
d. 时域信号分析测试
采用 MSO6000 系列示波器进行时域信号波形分析 , 主要测试参数包括时钟抖动,频率,电平及数据流分析。
