1 Scope

This procedure applies to the first inspection of quartz crystal frequency standards (including GPS-controlled quartz crystal frequency standards) Determination, follow-up verification and in-use inspection.

2 Overview

Quartz crystal frequency standard (hereinafter referred to as quartz frequency standard) refers to a high-stability quartz crystal made into a single device. Oscillator. It is mainly composed of a quartz resonator, an oscillating circuit, an isolation amplifier, an automatic gain control circuit, an oven, Precision temperature control circuit and DC stabilized power supply and other components. Quartz frequency standard has excellent short-term frequency stability and high frequency accuracy; stone controlled by GPS signal British frequency standard, its frequency accuracy can reach the level of atomic frequency standard. Quartz frequency standards are widely used in industrial production, national defense, scientific research and measurement.
