This note describes the operation of the major components used for controlling the phase and the field level of the PEP rf cavities. The block diagram of one rf station is decomposed into several control loops: each cavity has a tuners' servo loop which maintains the frequency constant and also keeps the field of each cell at the same level; the total gap voltage developed by a pair of cavities is obeying the command of the gap voltage controller; finally, the phase variation along the amplification chain and the klystron are compensated by a phase lock loop. The design criteria of each loop are set forth and the circuit implementation and test results are presented. The purpose of this report is to acquaint interested people with the design philosophy and to allow them to evaluate the capabilities of this system and its behavior during operation of the machine. 5 refs., 16 figs.
