89640A 基于PC的矢量信号分析仪（VSA）提供测量至2.7GHz的RF信号，例如LMDS、802.11b无线局域网、802.11a 和HiperLAN/2 OFDM无线局域网、蓝牙系统，以及其它信号的36MHz带宽。通过用灵活的解调分析新出现的宽带制式信号，它能帮助您设计新的数字通信系统。
使用89640测量RF信号及数字调制信号的调制质量。它灵活的调解性能不仅体现在处理宽带信号，也体现在处理窄带信号、基于某种标准的信号及特定信号。
89640分析仪具有独特的差错分析工具，包括自适应均衡，可帮助您确定是否有问题，以及问题的产生原因。它包括DSP差错，例如符号时序差错、过滤差错、DAC溢出、不正确的sinX/X补偿等，以及IQ不平衡、正交时滞、IQ偏移及其它RF问题。
这些能力也可用于在数学工具，如MATLAB和Mathcad建立的仿真上进行测量。在使用Keysight EEsof 先进设计系统CAE仿真时，能在“实时”方式的动态链接中进行这些测量。因而您能象在硬件中一样，对仿真进行查错和调整。
89640A矢量信号分析仪是基于模块VXI硬件的预配置系统，您可通过IEEE-1394FireWire(火线接口)界面用您的电脑对其进行控制。
