  1206B/C Specifications










  Model 1206B/C GNSS Synchronized Clock (40ns)

Built by Power Professionals, For Power Professionals
The Arbiter Systems® Inc. The 1206B/C GNSS Synchronized Clock is a multi-satellite system (GPS/GLONASS/Galileo/BeiDou) timing source for precision timing applications. Arbiter's next-generation sub-station clock provides enhanced performance and security (EPS) along with the wide range of functions you have come to expect from the Leader in timing for the Power Industry.

EPS benefits include multisystem timing sources, standard hold-over oscillator, multiple levels of security, secure communications, and anti-spoofing technology.

The Model 1206 is available in tw0 versions: the 1206B, 1205C, and the model 1206D. The Model 1206B has eight status LED's and LCD status back-light display and key-board. The model 1206C adds a large (20mm or 0.8") LED time display. Both versions have 72 receiver channels, capable of tracking optimum performance. Real time continuous estimation of actual holdover errors, oscillator trajectory prediction and high reliability architecture provides accuracy and stability allowing the model 1206B/C (100ns worst-case accuracy) to meet the requirements of a broad range of applications from relay synchronization to phasor timing.
