Polyastral type GPS time frequency comprehensive test instrument NKGT-12

The investment of this instrument is a special instrument and testing tools for the implementation of the East China and South China Power Grid unified clock system standard.
The measurement and calibration of power system (substation and power plant) of various clock device, realize the clock of a unified power grid.
The clock device manufacturing factory inspection (FAT) and engineering acceptance (SAT) and the pilot laboratory testing.
The power supply company, electric power transmission and transformation power generation company, company related business department.
The time stamped on power network automation system, computer data exchange network, the sequence of events recording device, fault recorder, microcomputer relay protection device is tested check regularly or irregularly.
All the instruments set time reference (GPS global positioning system), frequency standard source, time measurement, IRIG B time code generation and demodulation and decoding, pulse delay (phase shift) and random events idle contact pulse time records of multiple modules as a whole, has a special test, multi-functional, integrated, intelligent, the operation of a simple power system characteristics.
It can also track field within the L1 band (1575.42MHz) signals with 12 satellites, satellite tracking algorithm, real-time correction of transmission delay
