Abstract :
Principles of precision frequency measurement by use of electronic counters are discussed and limitations of frequency range extensions by the heterodyne method are outlined. A completely new frequency meter for use up to 42 mc/s is described which has the advantages of direct read-out, simple operation, and an accuracy of ± 1 part in 107 ± 1 c/s. Consideration is given to means of extending the frequency range into the V.H.F. and U.H.F. bands. A typical converter for the range 40 - 150 mc/s is described.
