Abstract : A high accuracy atomic frequency standard and clock which utilizes a microcomputer. The microcomputer compensates for aging and temperature variations in the atomic standard and its slave crystal oscillator and generates an error signal which is used to either correct the frequency of the slave crystal oscillator or to adjust the number of clock pulses per unit time interval. No C-field adjustment is employed.
