A fourth category of software-defined instrumentation for wireless test

The increasing demand for wireless data services is driving the development of wideband radio technologies and products. Technologies such as 802.11ac that utilize up to 160 MHz of bandwidth are on the market today, and 5G is expected to use up to 2 GHz to support bandwidth intensive applications. The test and measurement of such devices requires modern analysis equipment with stringent specifications. Furthermore, shrinking test equipment budgets necessitate newer, more creative and cost-effective approaches to testing devices. While software-defined radio (SDR) approaches to instrumentation have been on the market for many years, their price points have typically been high.
