Overview

About the TimeAcc-001

Specifications

By tracking BeiDou, GPS, or other external standard time sources, the TimeAcc-001 obtains a precise and stable time source to simultaneously monitor the time accuracy of master clocks and slave devices. Through the background network management system, it displays the time accuracy of the tested clocks in real time, provides early warnings of time performance degradation in the tested equipment, and performs statistical analysis on large volumes of monitoring data, achieving truly comprehensive time monitoring.

Key measurement features include: Simultaneous measurement of at least 12 channels of signals, with measured signals including 1PPS and DCLS, as well as monitoring options for NTP, PTP, SOE, GOOSE, serial messages, etc.; no dedicated software required, with built-in Web management displaying measured signal performance in real time; real-time monitoring of measured signal accuracy, with alarm information reported to the network management system; configurable accuracy alarm thresholds for measured signals; support for setting compensation values for each measured signal; independent management and configuration for each measurement port.

Key data recording features include: Recording the accuracy of each monitored clock device in real time; recorded data is saved in Excel format files, with the accuracy of each clock organized in separate columns for easy comparative analysis; equipped with a pluggable SD memory card, allowing the monitoring unit to store nearly a month of measurement data even if the network management system fails.

Also functioning as a precision clock, the TimeAcc-001 is equipped with 3 IRIG-B DC and 1 1PPS (TTL) output interfaces. When the original clock fails, it can take over as the master clock, increasing system redundancy and reliability.

Product Features:

● Real-time monitoring of hundreds or thousands of master clocks or slave devices via the network management system, providing both early warnings and statistical analysis ● Meets diverse user needs across various scenarios, supporting both local and remote measurement ● Standard monitoring of 6 pairs of signals (1PPS and DCLS), or optionally monitoring 12 channels of DCLS signals simultaneously ● Provides monitoring options for NTP, PTP, SOE, GOOSE, serial messages, etc. ● Functions as a standard time source; can serve as a backup master clock and generate SoE triggers via timed outputs ● Loopback monitoring using its own time outputs helps analyze abnormal channel jumps
