When Display EVM in Percent is not selected (default), PmblEVM data is expressed as a MER value in decibels (dB). When Display EVM in Percent is selected, PmblEVM data is expressed as a percent (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.).
