GAOTek Portable Time Analyzer with GPS

USD Call for Quote


GAOTek Portable Time Analyzer with GPS analyzes time and frequency synchronization and performs high-precision measurements and analyses based on the IEEE 1588v2 time and clock synchronous system. The precision GPS, BD and GPS-controlled rubidium clock or OCXO produce high-precision UTC time and generate high-precision clock which is taken as a time reference for measurement. The analyzer is able to measure the synchronization accuracy and performance based on SyncE clock synchronous system, supporting G.703 2.048 MHz, 2.048 mb/s. It works with TD-SCDMA, TD-LTE, FDD-LTE, CDMA, CDMA2000, etc. It is used in R & D, production, installation, commissioning and maintenance, etc.
