Time correction product
is a set of high-precision time and frequency recovery equipment, which can track
time and generate a variety of precise time signals. It applies
locked high-performance constant-temperature crystal oscillator (optional rubidium atomic oscillator) technology to provide timing output while combining the excellent short-term stability of the local clock and the
long-term stability.
.
The versatility of time correction products
makes them suitable for use in various fields (
, metallurgy, communications, electric power, finance, radio and television, security, transportation, water conservancy, national defense , petrochemical, medical, government agencies, education, etc.). The products produced by Jinan Weishang Electronics Co., Ltd. are standard
