89640A Agilent Vector Signal Analyzer

Additional Features:

• DC-2.7 GHz frequency coverage with 36 MHz of analysis bandwidth
• Optional second IF/baseband channel for direct baseband I & Q input
• 24 digital demodulators with settable center frequency, symbol rate, filter type and alpha/BT
• Agilent unique error analysis features, including EVM over time, phase/amplitude/frequency variation over time, adaptive equalization and more
• 25 standards-based measurement setups including GSM (EDGE), cdma2000, W-CDMA, PHP, 1xEV-D0, TD-SCDMA, 802.11a/b/g (WLAN), digital video signal analysis and more
• Dynamic links to and from ADS data to troubleshoot simulations and create "virtual hardware" to substitute for block diagram elements not yet realized in hardware
• Up to 1.2 GB of signal capture and playback memory to record signals or transients for analysis later

The Agilent 89640A measures 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 Agilent 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 Agilent 89640A vector signal analyzer is a modular, pre-configured system based on modular VXI hardware and controlled by your PC via an IEEE-1394 "FireWire" interface.
