a.EVM and frequency error specifications apply when the Burst Sync is set to Training Sequence.

b.The definition of accuracy for the purposes of this specification is how closely the result meets the expected result. That expected result is 0.975 times the actual RMS EVM of the signal, per 3GPP TS 45.005, annex G.

c.This term includes an error due to the software algorithm. The accuracy specification applies when EVM is less than 1.5%.

d.tfa = transmitter frequency × frequency reference accuracy
