cdma2000/CDMA 测试
随着工业需求的成熟和发展，码分多址（CDMA）技术也在成熟和发展。CDMA 是一项基于 TIA/EIA IS-95 CDMA 标准（包括IS-95A 和 IS-95B 两个版本）的数字蜂窝技术，首次面世是作为一款话音通信解决方案。它使用直接序列调制（带数字编码）来扩展其频谱。
随着用户设备和应用软件的发展，CDMA 已为 cdma2000 让路。cdma2000 是由电信工业联盟开发的一种技术，在 1.25 MHz 单一信道中支持电路交换话音通信以及高达 307 kbps 的分组数据传输速率。
另一种从 CDMA/cdma2000 演变而来的技术是 1xEV-DO（1x Evolution, data only）。关于此项增强的 cdma2000 空中接口技术（优化了分组数据传输）的详细信息，请参见 Agilent 1xEV 技术页面
安捷伦科技公司为工程师和技术管理人员提供 cdma2000/CDMA 产品、解决方案和服务，帮助他们进行下一代网络的设计、集成、制造和性能优化。在您推动 CDMA 的创新和发展的道路上，安捷伦为您披荆斩棘。

Agilent Technologies Introduces 6-GHz Signal Generators with Industry-Best Performance
Today's aerospace/defense environment requires enhanced radar performance to detect weak signals at long distances. To provide the pure and precise signals needed to test these designs, the MXG uses an innovative triple-loop synthesizer to deliver phase noise performance of -146 dBc/Hz at 1 GHz and 20 kHz offset. For developers of radar components such as mixers and analog-to-digital converters, the MXG also features industry-leading spurious performance of -96 dBc at 1 GHz.
