GAO Tek Time/Frequency Sync Analyzer

Time/Frequency Sync Analyzer absolutely complies with latest ITU-T time/frequency test standards, and provides high precision measurement, study and assessment on the time/frequency indexes.




The Time/Frequency Sync Analyzer, with the high-precision background, and all-in-one design, is designed for comprehensive measurement on time/frequency synchronization performance. It complies with latest ITU-T time/frequency test standards and provides high precision measurement, study, and assessment on the time/frequency indexes. It supports SSM, EMSC transmits and receive, auto recognize SSM Rx channel, end-to-end measurement on packet delay variation (PDV) and dual PTP/SyncE interfaces (100M/1000M/10G) at Master/Slave end. Moreover, it can examine dTE time signal noise and cTE statistic deviation and evaluate path skewness index. Furthermore, it also contains an auto manual and timer test modes. Some common applications of this device include R&D, production, commissioning, and verification for mobile backhaul and IP Carrier Network in which full-featured time/frequency measurements are significantly needed.

  • Complies with IEEE, ITU-T standards
