Abstract:

An existing transistorized frequency standard was completely redesigned in order to improve its operation and make it more suitable for our particular applications. The crystal and oven were the only components retained in the new design. The design and performance of the modified frequency standard are described. One of the original design criteria was to keep the oscillator inexpensive, yet stable and reliable. This implies that the design should be as simple as possible. Another desideratum was to use transistors as the active elements thereby allowing the whole circuit to be battery operated hopefully with low power consumption and to be mounted in the oven. Also, it was decided to build the system with high thermal inertia so that, in the event of heater power shutoff, the frequency drift would be minimized. Author
