FOREWORD

This standard describes a test method for measurement of transistor noise figure and effective input noise temperature at MF, HF, and VHF.This method is a revision of RS-311 and incorporates material previously found in RS-283, and as such rescinds RS-283 since it was found deficient in test method details and definitions for noise figure measurements. Also, RS-311-A adds the necessary information to make "effective input noise temperature" measurements. The noise definitions are identical to that found in JEDEC Standard No.77 and do not conflict with the IEC documents, found in 47 (Secretariat) 558/548 as approved in Tokyo, June 1975.
