ABSTRACT
This paper describes a HP8510B Network Analyzer measurement system that has
been configured with 2.4mm coaxial connectors to take advantage of higher
resolution time domain measurements achievable by sweeping .045 to 40, or 50
GHz. High resolution provides improved ability to accurately identify closely
spaced discontinuities, which is critical to the successful design of next-
generation broadband components.
A comparison of measurement results is shown using the 2.4mm and K connector
to 40 GHz, and with the 2.4mm connector to 50 GHz.
AUTHOR
Julius Botka was born and educated in Hungary. He joined HP in 1966 and has
worked on the development of microwave components and standards for the HP
8407, HP 8755, HP 8505, and HP 8510A/B Network Analyzers. Recent achievements
include the design of the .045-26.5 GHz Directional Bridge for the HP 8513A
and HP 8515A test sets, t~e concept of the 2.4mm connector family, and the HP
PSC Precision Slotless Connectors in type N, 3.5 and 2.4mm. Julius is cur-
rently R&D Project Manager for Microwave Components and Standards at HP's Net-
work Measurements Division, Santa Rosa, California.

Broadening continuous frequency
capability in network measurements
is making high resolution time
domain a reality. This paper will
give an overview of the capability
and how it may be used in the
design of the next generation of
microwave components.
