Frequency Measurement in Compliance with ITU-T G.8273.2


The accuracy of T-BC plays a key role in the implementation of high-precision time synchronous network in LTE-A , TDD-LTE and 5G. In order to meet the new consistency requirements, three profiles has been published successively including ITU-T G.8273.2, G.8273.2 Amendment1 , G.8273.2 Amendment 2(01/2019). 

In ITU-T G.8273.2 recommendations it puts forwarded four test items including cTE/dTE analysis, noise transfer, noise tolerance and phase transient.

We provide test solutions regarding boundary clocks in accordance with ITU-T G.8273.2.
