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
RCE (EVM)
c
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 “PreambleData” and
Pilot Tracking is set to Track Timing/Phase/Timing all on state.
