Stim Eq IQ Ref (Component Test)
The trace is the equalized, source-side counterpart to IQ Ref: the reference IQ signal used for the stimulus source channel's equalized 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. comparison, per the EVM Equalization and Include Unbalanced in EVM Equalization controls (see Eq IQ Ref for how the two equalization choices behave).
This trace only has contents when Reference = Measured Stimulus and Computation Mode = Statistical.
