Report EVM in dB (LTE)
Cleared
specifies the EVM Error vector magnitude (EVM): A quality metric in digital communication systems. See the EVM metric in the Error Summary Table topic in each demodulator for more information on how EVM is calculated for that modulation format. units for all traces.
When is selected, EVM will be reported in dB.
When is cleared, EVM will be reported in %rms according to the LTE Long Term Evolution standard.
The reference for EVM calculation in both cases are the ideal IQ points which are shown on the IQ Ref and IQ Ref Time traces.
