The biggest feature of the taming clock is the fast locking speed. In an open area, the frequency accuracy can reach 5E-9 within 3-5 minutes, that is, the accuracy reaches 0.05Hz@10MHz Use the GPS timing function to adjust the clock to make the clock more accurate The basic principle of the GPS taming clock is to use the standard time signal output by the GPS module, generally a second pulse (1pps), to control or compare the frequency of the constant temperature crystal oscillator, and then output a signal to correct the frequency error of the constant temperature crystal oscillator Made of high-quality materials, sturdy and Easy to use, wide range of applications Power: Dc11.7-12.9v less than equal 15w Gps Antenna Power Supply: Dc3.3v 10m Output: Sine Wave, 1vrms ( 13dbm+-3db) Rs232 Output:Gps Nmea Signal Accuracy:Above Than Ocxo 2 Order Of Magnitude Plug Type: US Plug, it applies to Canada, India, Mexico, Thailand, Taiwan, the , the Philippines and so on.
