Software-defined radios (SDRs) can be instrumental in achieving reliable test and measurement (T&M) results for RF applications. In this article, learn about the basic concepts of an SDR, including the building blocks of the general system and its capabilities, the main applications of SDRs, and some of its advantages over conventional devices. Plus, discover how SDRs can be applied in T&M systems and how they affect the development of wireless devices.

The way most modern cross-correlation phase noise analyzers determine this figure is by approximating its value. Calculation of the noise floor approximation occurs during data acquisition of a device under test (DUT), which helps estimate the measurement margins. No matter the manufacturer, the measurement noise floor is unique for every analyzer.

Wireless connectivity has grown exponentially, causing the IoT market to expand as well. By 2030, the expected number of active IoT devices is predicted to surpass 25.4 billion. Because each country has specific certification/authorization requirements and standards, regulatory testing for Wi-Fi 6E devices is necessary.

Mismatch loads can be used to test amplifiers and help characterize their performance under conditions that might occur in the field. To do so, a mismatch load (or mismatch termination) is used to present a specified VSWR, rather than the usual 1:1 perfect 50 ohm load.
