It calibrates, measures and verifies the time synchronization accuracy of substation automation equipment, protection relays, merging units and secondary power devices, ensuring unified standard time across the whole power system.

Q2: Which industry standards does this tester comply with?

A2: It fully complies with DL/T 1100.1-2016, DL/T 1100.2-2013, IEEE 1588 international timing specifications and provincial grid time synchronization technical requirements, all test data is accepted for power station inspection and acceptance.

Q3: What timing signal types can the instrument identify and test?

A3: It automatically identifies & tests IRIG-B AC/DC code, pulse signals, serial time messages, SNTP, NTP, PTP(IEEE 1588), SV, GOOSE, FT3 messages and other mainstream power timing signals.

Q4: What timing reference sources does the tester adopt?

A4: It supports GPS + Beidou dual-mode satellite timing. Built-in high-stability oscillator provides high-precision local clock benchmark when satellite signal is unavailable.

Q5: What is the highest time measurement resolution?

A5: Equipped with high-speed AD sampling module, the time measurement resolution reaches up to 4ns, which can capture tiny time deviation accurately.

Q6: Can it conduct continuous long-term monitoring of timing signals?

A6: Yes. You can manually set arbitrary monitoring duration, record whole-process data, calculate accuracy, standard deviation, peak value and pulse width of timing signals automatically.

Q7: Does it support network timing accuracy testing?

A7: Definitely. It measures synchronization precision of PTP, NTP and SNTP messages under 10/1000M Ethernet network environment for network-based time synchronization systems.

Q8: What is SOE measurement function for?

A8: The SOE delay test function checks the event sequence recording accuracy and transmission delay of merging units, smart terminals and protection devices, which is essential for substation commissioning.

Q9: Can it output abnormal timing signals for equipment anti-interference testing?

A9: Yes. It can simulate faulty abnormal time signals to examine the response capacity, stability and fault tolerance of on-site secondary control devices under abnormal timing conditions.

Q10: Can multiple timing signals be tested and compared simultaneously?

A10: Supported. Multi-channel input design allows accessing several timing signals at the same time, convenient for transverse comparison and difference analysis of different clock sources.
