If you are an RF designer, you are probably beginning to see the appearance of more and more digital baseband and IF interfaces. You need to continue performing modulation quality measurements on these interfaces. If you are a digital baseband designer, you are likely to face constant trade-offs between signal quality and power consumption and battery life. You need signal analysis measurements to find the optimal encoding and filtering designs. A digital vector signal analyzer would be the perfect tool for both these applications.

This application note describes the characteristics, setup, and operation of a digital vector signal analyzer (VSA) created by combining an Agilent logic analyzer and 89601A vector signal analysis software. Whether you are an RF or baseband designer, this combination of logic analysis with vector signal analysis enables you to access a robust suite of signal analysis measurements from the same software console, saving you valuable time in test and debug.
