RF Connector Grade Definitions

Metrology-Grade

Metrology-grade is best suited for calibration applications where the highest performance and repeatability are required. The female connectors in these adapters have slotless connectors. Precision slotless connectors prevent diameter variations in the female center conductor, therefore allowing greater control over connector impedance, unlike instrument-grade or general purpose connectors. 

Instrument-Grade

Instrument-grade is best suited for measurement applications where repeatability and long life are primary considerations. Instrument-grade connectors are intended for use with precision test and measurement equipment where maintaining high performance through many connect/disconnect cycles is of paramount importance. They feature the traditional slotted female contacts. 

General-Purpose Grade

General-purpose grade is intended for economy use on components, cables, and microstrip, where limited connections and low repeatability is acceptable.
