Francis Edgington is a vice president of HEYS Professional Services, Inc. and an active consulting engineer for digital and analog RF and microwave measurements. He retired from Agilent Technologies (Hewlett Packard), Santa Rosa, Calif. in March of 2003 after 24 years of service.
His last eight years at Agilent was as a Customer Support Engineer for spectrum analyzers. As a response to customer inquires, he developed and presented Agilent’s application of the Vector Signal Analyzers for digital measurements needed in the CATV industry. He has helped his customers solve real-world problems encountered in deploying CATV digital services of downstream digital data/video, bursted upstream cable modem, and digital telephony.
His support of the 8591C CATV Analyzer enabled it to become the “standard” for analog TV FCC proof of performance measurements. Francis also assisted equipment manufacturers to programmatically measure common CATV parameters by using 8591C measurements under computer control. He also helped equipment manufacturers use lightwave and precision spectrum analyzers for manual and computer controlled high dynamic range CATV measurements.
He consulted with R&D to develop the CATV measurements personality on the ESA series spectrum analyzer and wrote ESA series option 227 CATV personality datasheet and set specifications.
