Precision and accuracy has fascinated me since before I can remember. In the days before GPS and internet access to time servers, I bought a battery-powered quartz crystal wall clock — the then state-of-the-art. It amused me to trim its oscillator to see how closely it could synchronize to the time signal from CHU (Canada's equivalent of WWV).
Fortunately, modern timekeeping is now entirely automated. A GPS receiver or a rubidium atomic clock are all that are needed to provide accurate or precise time and frequency reference signals to modern electronics.
If you want to take timekeeping to a new level in your application or require a precise reference frequency for your electronic project or test lab, check out our catalog of modules.
