  • Learn how switch matrices can be used to extend the port count of VNAs to meet the testing demands of the latest wireless standards and sensing technologies.

  • Extending a VNA with a matrix switch can be one of the most cost-effective, modular, fastest, and least resource-intensive methods of reaching a desired port count.

  • A complex testing scheme usually involves integrating multiple pieces of equipment from multiple manufacturers. This article discusses the differences in proprietary and generic interfaces, the benefits each type has to offer, and provides some solutions to potential interface barriers and how to remove them.

  • As manufacturers move to higher frequencies, development and testing of the latest wireless systems/devices require specifically designed test systems that can emulate a complex environment with a greater mix of device types.

  • Fixed RF attenuators are versatile components that not only provide useful level control features but can be used to enhance the return loss at the input of a mismatched component/device in the signal chain. This article explains how RF fixed attenuators are used in hopes of improving the VSWR within the signal chain.
