A “proper” timing device with antenna is a sub $100 sort of thing. It will be < 100 ns pretty much forever and ever.
Yes - understood. The system I am building needs to generate a gate on a known zero-second boundary. At the moment I am working on a three-tier system...
1. Windows PC providing a gate about one minute duration (+/- 30 seconds around the required zero-second). Hopefully Windows can manage that... 2. Microcontroller identifying the zero-second within that minute and providing a gate +/- 500 ms around the zero-second. 3. And-ing the 1 PPS signal with this gate to clock the final output gate opening.
