3 Spectrum Analyzer Mode
3.2 Swept SA Measurement
The Open Short calibration is applied by taking the average of the Open and the
Short trace. The average is a linear average point-by-point. You can further
configure averaging on the traces (Open, Short, and final measurement). In this
case, the value of the averaged Open and Short trace are linear averaged (by
performing a point-by-point average of the two traces). Both the Open and the
Short terminations should have approximately unity reflection. Taking the average
gives the best estimate of a perfect reflector for a scalar return loss measurement.
You should store the result in reference trace 3, for later application with the
Normalize function.
