 To complicate matters, EVM is a unit-less measurement. It's a ratio, which can be represented in both percent (%) or as a dB (converting to log scale). Since dB will show you in details where the differences are - it's easier to understand the difference between 2%, 1% and half a percent by discussing -34 dB, -40 dB, -46 dB (which are the same physical error).  Typically EVM performance of less than -35 dB is required for many communications applications. To complicate matters, EVM is a unit-less measurement.
