Abstract
This is the first of a series of reports describing the automatic cavity tuning servo to be incorporated in the DSN prototype hydrogen maser frequency standard. It is a first-order sample data control system, featuring stability monitoring circuits for the detection of malfunction in the maser and its receiver-frequency synthesizing system. The control system ignores error measurements exceeding an adjustable limit. The system’s counter calibrates the Zeeman oscillator used to correct the maser output frequency for ambient magnetic field.
