Understanding CDMA Measurements for Base Stations

Application Notes

This application note presents the fundamental measurement principles for the RF parametric tests performed on Code Division Multiple Access (CDMA) base stations and their components. It primarily focuses on selected tests specified for the IS-95-based systems, although other tests commonly made in the industry are also covered. While these measurements are made in most phases of the product lifecycle, the emphasis is on those tests made in manufacturing and product development/ design verification. Mobiles are not covered because they have unique testing challenges.


The CDMA industry is growing rapidly throughout the world. For a variety of technical, economic, and even political reasons, base stations are becoming smaller, using less power, costing less, covering a smaller area, and providing higher capacity than ever before.
