Wireless technology is synonymous with RF and microwave signal frequencies, although it’s steadily moving higher in frequency into the millimeter-wave (mmWave) range. As a result, the test equipment needed to design, develop, and maintain wireless products must constantly evolve to higher frequencies and more advanced signal formats.
With ever-increasing numbers of wireless products in use, competition grows for available frequency spectrum. It’s essential for testing to ensure that wireless devices designed to emit signals don’t exceed their limits and interfere with nearby equipment. Fortunately, high-frequency test equipment suppliers represent an innovative group that has developed effective measurement solutions for wireless testing. A sampling of such test gear is reviewed here.
