Higher frequencies are more important than ever, as 5G communications, satellite communications (satcom), and radar applications all plan to utilize a wide range of frequencies that extends into millimeter-wave (mmWave) bands. That means test-and-measurement companies must keep up by providing equipment that can generate mmWave signals with very wide bandwidths. These companies must also support other components like complex modulation schemes and multiple-antenna techniques.
To satisfy these demands, Keysight Technologies recently launched the VXG Series of microwave signal generators. The series consists of the M9384B VXG benchtop instrument (see figure) and the M9383B VXG-m modular PXIe version.
