IQ Rotation
Rotates the IQ Meas/Ref Time data and corresponding ideal state positions by a
user defined amount ranging from -360 degrees to 360 degrees. The Rotation
parameter affects the IQ Gain Imbalance and Quadrature Skew error data results.

IQ Normalize
Turns IQ Normalize on or off. When IQ Normalize is on, the Meas Time and Ref Time
data is normalized so the extreme points have a value of 1. For quadrature
modulation types, the outermost points of the constellation are normalized to 1. For
FSK constellations, the deviation is normalized to 1.
When IQ Normalize is turned off, the actual data values based on the input signal
level are plotted on the constellation.
When normalization is ON, the instrument normalizes or scales the demodulated
trace data results to a nominal value of 1. Normalization is performed on these
traces:
–
IQ measured time and IQ measured spectrum
–
IQ reference time and IQ reference spectrum
–
Error vector time and Error vector spectrum
