SubscribeTIME & Frequency Solutions are proud to present their latest addition to their range of precision timing instruments.
So far as is known, this is the only instrument of its kind available today. The new TimeAcc is a state-of-the-art portable unit, which uses an integral GPS receiver to calibrate the internal precision oscillator. Once calibrated, the unit can then be taken indoors to precisely measure the time accuracy of a range of time signal inputs against GPS. The difference calculated is clearly displayed on the large, full colour Windows-based touch-screen.
TimeAcc is invaluable where time of day information is distributed from a central master clock to sub-master clocks or user systems over large distances via serial data links or packet networks. Substantial delays can occur due to high levels of network traffic or even due to the long distance between the master clock and the user. Some commercially available software algorithms can reduce these errors but, unless the errors are accurately and independently measured at the point of use, the user cannot be certain of the accuracy of his time source in this type of application.
Additionally, the high accuracy of the TimeAcc means that it can also precisely measure the time error of free-running clocks and timing systems which are synchronised from untraceable sources, such as television and radio broadcasts, electrical power lines and via the internet.
As the unit is portable and battery powered, it is simple to synchronise the unit to GPS outside by using the integral GPS antenna. Alternatively, synchronisation can take place inside if connected to an external GPS antenna, with the additional flexibility to use AC mains power.
