Multimode Clock Box

Introduction 

CL-3000 is a multi-mode timing clock equipment. This equipment can be timed by the GNSS satellite and PTP timing. It can output the GNSS synchronized accurate reference signal and time information.

In the absence of GNSS signal, It can automatically switch to the holdover function or PTP network timing to ensure the stable operation of equipment.

The user can manage the equipment by the serial port .It widely used in the applications of communication, power industry, military, scientific research, instrumentation and other industries.

Application

Scientific research institutions/Private network   

 • Provide frequency meter, oscilloscope and equipments needing frequency testing a wide range of frequency serial port as a testing benchmark.

 • Be used as a reference, cesium rubidium frequency standard, mutual backup.

Communication

• Support PTP timing devices for the master or slave clock signal.
• Provide the test equipment with basis time and frequency with high precision reference or the frequency reference of 1PPS.

Broadcasting

• Clock synchronization reference source is an effective and necessary device in a single-frequency network construction. It can easily provide a 10MHz clock and 1PPS reference time at any synchronization systems.
