Description

FOREWORD

Members of the P-5.3.1 Working Group have long known the need
for the provision of accurate impedance standards in 75-ohm coaxial
measurements. These standards will be necessary for the
qualification of the connectors, standards for which are now being
prepared by P-5.3.1. The only practical means for obtaining these
standards is by constructing them with precision coaxial
connectors. This opens the door for more precise instrumentation
and for certification by the National Institute of Standards and
Technology. Precisely calibrated adaptors shall therefore permit
conclusive qualification and testing of the field connectors to be
specified in forthcoming P-5.3.1 standards documents. The precision
connector facilities will also permit conclusive calibration of the
various equipment and components employed in the communication
industry.

The purpose of this standard is to describe the requirements for
the precision impedance standards to be specified for 75 Ohm
coaxial measurements in standards for R.F. connectors.
