A New Automatic Frequency Regulation System (Correspondence)
J. R. Singer · IEEE Transactions on Microwave Theory and Techniques · 1960
A considerable number of frequency regulation systems for voltage tunable sources such as klystrons are presently available. The most prominent of these is the pound Regulator which provides an excellent stable source. Perhaps the only disadvantages of the Pound system are the initial cost and the rather critical adjustments necessary when starting up.
