IMS-GPS Clock
SKU: IMS-GPS Clock
GPS Satellite Receiver
The frequency locking of the master oscillator to the GPS-system enables this module to generate fixed and programmable standard frequencies with high accuracy and stability. Various oscillator options allow the cost efficient implementation of different requirements concerning the accuracy of the outputs.
The pulse generator of IMS-GPS Clock module generates pulses per second and per minute. Four programmable outputs are also available. The pulses are Synchronised to UTC-second.
Key Features
- 12 channel GPS C/A-code receiver
- Oscillator Options: OCXO-SQ, OCXO-MQ, OCXO-HQ, OCXO-DHQ
- Pulses per second and per minute
- RS-232 interface
