All Lockit devices have their timecode oscillators factory calibrated to GPS reference with an accuracy of at least 0.1ppm (parts per million). That means that they can run independently while drifting way less than half a frame from this reference over 24 hours.
If you are interested in the math behind it:
- 24h * 60min * 60sec * 30fps = 2,592,000 frames per 24h
- 2,592,000 frames * 0.000,000,1 = 0.26 frames aberration
But it gets even better!
As soon as you enable C-Jam in your ACN network, all Lockit devices on set will monitor their oscillator speeds in real-time and make adjustments as necessary to eliminate the last bit of drift. With C-Jam enabled you can run forever with an accuracy of 0.0ppm!
