Product Description


This time and frequency analyzer analyzes time and frequency synchronization, and it performs high-precision measurements and analyses based on the IEEE 1588v2 time and clock synchronous system. It works with TD-SCDMA, TD-LTE, FDD-LTE, CDMA, CDMA2000, etc. It is used in R&D, production, installation, commissioning and maintenance, etc. The Internal 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 2.048MHz, 2.048Mb/s. The product performs precision and performance measurement of time synchronization on transmission devices, like IEEE1588v2 time server, PTN/OTN/xPON etc, and base station devices, supporting 1PPS+TOD interface, and IEEE1588v2 PTP interface.

It also performs statistics and analysis on time signal with random deviation and makes the creative asymmetric compensation measurement. It works as supplementary time server and provide time information to the system by using 1PPS, 1PPS+TOD or IEEE 1588v2PTP signal output from the analyzer, and output high-precision clock signal. Additionally, it provides TOD second pulse state of 1PPS+TOD, and the time level & self-defined priority function of PTP, so as to verify the performance of the devices. Test results can be uploaded to PC by GAO Test Console via USB port. Also this PC software can output the results in Excel, HTML, and PDF format. The product has a long battery life and capacity to store large amount of data. There is a 7 inch TFT color display which provides touch screen menu-driven operation, graphical display of test results. It can set up the auto test system or remote test system for the manufacturing sectors. The testing could be also setup manually.

  • Real-time capture and display TOD messages, store test results of TOD seconds deviation
  • Real-time capture, analyze and save PTP packets
  • Real-time display PTP protocol synchronization process, and show the grand clock information
  • Operate one or more analyzers in the same network by remote control with specific software and perform various measurements
  • Perform statistics and analysis on the long term wander performance of time/clock synchronization, calculate MTIE, TDEV, MRTIE, MDEV, ADEV, RTIE, and make comparison with masks of G.811, G.812, G.813, G.823, and G.8261
  • Perform self-calibration by connecting GPS antenna and fixing satellites for 25 hours
  • Provide complete SCPI instruction set.
  • Portable, lightweight and robust design
