CMMB measurement application for CXA

Manufacturer's part number :


Manufacturer Agilent Technologies

Keysight Technologies

Description :

The CMMB measurement application for the CXA is one of more than 25 measurement applications in the Keysight X-Series, evolutionary approach to signal analysis that spans instrumentation, measurements, and software, transforming the X-Series signal analyzers into standards-based transmitter testers. The CMMB application provides fast, one-button standard-based power and modulation analysis capabilities to help your design, evaluation, and manufacturing of CMMB modulators, transmitters, amplifiers, tuners, and gap-fillers/repeaters.
