Hello, I have developed a module using 54L15 and am currently measuring its RF performance. On Rohde & Schwarz instruments, I have observed numerous test results regarding EVM, but I am unsure which parameter on the instrument corresponds to the EVM specified in the chip datasheet.
As shown in the figure above, the EVM parameter in the datasheet is 2%rms, but my measurement results are: Abs.RMS EVM Overall (%)：13.39 %rms, Off.RMS EVM Overall(%) ：2.154 %rms. Both seem to exceed the specified limit. Which parameter should I record?
