Digital Cable TV measurement application for CXA

Manufacturer's part number :


Manufacturer Agilent Technologies

Keysight Technologies

Description :

The DVB-C digital cable TV measurement application is one of more than 25 measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements and software, transforming the X-Series signal analyzers into standards-based transmitter testers. The DVB-C application provides one-button, standard-based power and modulation analysis capabilities to help design, evaluate and manufacture digital cable exciters and transmitters. The DVB-C measurement application includes three standards of digital video broadcasting over cable TV: J.83/A (DVB-C), J.83/B (DOCSIS DS) and J.83/C (ISDB-C).
