Opportunities abound as do challenges. To unleash the 5G business potential, chipset and device engineers must overcome significant challenges in the technology evolution and revolution: millimeter-wave (mmWave) propagation and channel modeling, wideband calibration, antenna complexity, 3D beamforming, over-the-air (OTA) measurements, protocol optimization for peak data throughput, digital interface capacity, battery life; the list goes on.

Keysight Technologies is touring the U.S. and Canada, offering day-long test drives of the latest RF signal analyzers, network analyzers, oscilloscopes and bench instruments. See when they are coming to your area.

This is the fifth and final installment of a Keysight Technologies' application note discussing practical strategies to overcome RF/microwave interference in the field, using real-time spectrum analysis.

Test software solutions are invaluable throughout the product development lifecycle. They speed up product design by turning raw measurement data into information that engineers can use to make informed decisions and trade-offs from R&D through deployment.

At the beginning of every new product program, tremendous amounts of time, attention and money go into defining and integrating the required test system. The system is used to test the new products, ensuring that they function at the required levels and remain highly productive. The system is also expected to last for the life of the program.

 For active antenna arrays, a significant amount of production test time is spent on calibration.  Large arrays can consist of hundreds or thousands of elements and it is necessary to characterize the phase and gain alignment between these elements to ensure precise beam-forming.  In addition, the test time to align these elements can increase dramatically as the number of elements increases.  Hence, the ability to accelerate test by using multiple coherent measurement channels is a significant benefit.
