Extending the Life of Test Systems that Support Long-term Programs

Jim Curran, Keysight Technologies, Inc. (formerly Agilent Technologies electronic measurement business)

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.

Reducing the Test Time Required to Calibrate a Multi-channel Antenna

By Dave Brannon and Alex Dickson, Keysight Technologies, Inc. (formerly Agilent Technologies electronic measurement business)

 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.
