Sandwich Box Mark 3
The Mark 3 version of the Sandwich Box independent vibrator test system is under the final stages of development and testing. Once the development and testing has been completed the new mark 3 version will boast the benefits of:

Differential inputs
Externally triggered by TTL
Easier more flexible software

GPS – Position Option
Our ever popular GPS Synchroniser has had the new addition of being able to record the GPS positioning of the unit when triggered.

The addition of the CSAC (Chip Scale Atomic Clock) has given our auditors an instrument with accuracy of 1 ppb (part per billion). This is equivalent to a drift of 3 seconds per century.
