Now -with Varian's new line of high Q Cavities, frequency
stabilized local oscillators (Stabs) utilizing direct cavity stabilization
are commercially practical. Varian Stalo Cavities provide a very high
degree of short time frequency stability. Stabilization is completely
independent of the frequency of oscillator fluctuations and external
disturbances ... an inherent advantage over electronic stabilization
systems utilizing the feedback principle. Elimination of all electronic
components except the klystron oscillator also affords greater reliability
and longer life.
The ratio of the oscillator modulation sensitivity to the modulation
sensitivity of the stabilized oscillator defines the stabilization factor
of the cavity. Varian Stalo Cavities are available in three models -
VA -1280, 1281 and 1282 -offer stabilization factors from 15 to 160
. cover a wide range of important applications, including stabilization
of signal sources in high power klystron transmitters...
airborne uses in conjunction with receiver local oscillators
. laboratory testing. When used with Varian's new
highly stable reflex klystron oscillators, stability
comparable to that of many crystal controlled
oscillators can be obtained.
