The 89640A PC-based vector signal analyzer (VSA) offers 36 MHz of analysis bandwidth for measuring signals from DC to 2.7 GHz. Use the 89640A to measure the RF and modulation quality of digitally modulated signals. Its flexible demodulation features work equally well on wideband and narrowband signals, proprietary signals and standards based signals. The 89640A VSA features unique error analysis tools that are designed to help you identify physical layer problems and investigate their cause. These problems include symbol timing errors, filtering errors, DAC overflow, and incorrect sinX/X compensation as well as RF problems such as IQ imbalance, quadrature skew, IQ offset, and much more. These same capabilities can also be used to make measurements on simulations created by math tools, such as MATLAB and Mathcad. When used with Agilent EESof's Advanced Design System (ADS) CAE simulation, these measurements can be made in "real-time" using an optional high-speed dynamic link to the ADS. This allows you to troubleshoot the simulation, adjust it, and make measurements like you would in hardware. The 89640A vector signal analyzer is a pre-configured system based on modular VXI hardware and controlled by your PC via an IEEE-1394 "FireWire" interface.
