An ever-increasing base of demanding users in communications, timing, synchronization and other applications take advantage of this performance.

Packaged in a 2U, 19" rack mounted chassis; the CsIII weighs less than 30 lbs.
Standard features include 5 and 10Mhz sine wave outputs, a 1 PPS output and an RS-232 interface used to monitor and control the unit.
Optional T1/E1 telecom outputs and a portability kit are also available.
The portability kit replaces the rack mounting brackets with a movable handle and hard shell carrying case making it ideal as a remote calibration standard.
