IQ Ref (Component Test)

Menu Path: Trace > Data > Component Test > EVM > Channel N > IQ Ref

The IQ Ref trace shows the reference IQ signal for the channel, time-aligned to the measured signal, as a time-domain trace sampled at 2 samples per symbol. The I and Q values are normalized (unitless).

This is the signal the measurement compares IQ Meas against when computing the Error Vector Time trace and the EVM summary result. It also serves as the stimulus input to the AM/AM and AM/PM linearity fits.

To view the data as a constellation, select the I-Q trace format (Trace > Format > Format:).
