a. This term includes an error due to the software algorithm. It is verified using a reference signal whose
center frequency is intentionally shifted. This specification applies when the center frequency offset is
within 5 kHz.
b. tfa = transmitter frequency
× frequency reference accuracy.
c. RCE(EVM) specification applies when 10 MHz downlink reference signal including
QPSK/16QAM/64QAM is tested. This requires that Equalizer Training is set to “Preamble, Data &
Pilots” and Pilot Tracking is set to Phase/Timing on state. It also requires that Phase Noise optimization
mode is set to "Best close-in [offset < 20 kHz]".
