Product introductionProduct introduction
product description 
PPS synchronization accuracy tester, also known as PPS Tester, is a system clock synchronization accuracy testing equipment based on the 1PPS measurement method developed by Yi Xing Technology. It consists of hardware module ETS2110, host computer software ePPSTester and related accessories. PPS Tester supports the continuous collection and testing of 24 channels of PPS signals 24 hours a day, and the equipment test accuracy is as high as ±8ns.
PPS Tester helps evaluate the time synchronization stability of the entire system and discover unexpected bugs in the software, thereby ensuring the implementation of functional scenarios based on time synchronization.
