Eq Error Vector Time (Component Test)
The trace is the equalized counterpart to Error Vector Time: the normalized error vector (measured minus reference), in percent, between Eq IQ Meas and Eq IQ Ref after the estimated linear channel response is compensated. This trace is only computed when Computation Mode = Statistical, and drives the EVM (eq) summary result.
How the compensation is applied depends on the EVM Equalization control: with Apply Inverse Channel to Measured (the default), the inverse channel response is applied to the measured signal; with Apply Forward Channel to Reference, the channel response is applied to the reference instead (more numerically stable when the channel response contains deep nulls). The Include Unbalanced in EVM Equalization control determines whether the unbalanced channel term is included in the compensation.
