When both fixture simulation and port impedance conversion are on, all Z0 of the ports
to be saved must be set to the same value. If Z0 is different among the ports, no error
occurs, but only the Z0 of the smallest port number is output to the header.
When the time domain function is on, the saved data are not the displayed data but the
data of the S parameter before conversion.
For data saved in touchstone format, data operation, time domain, parameter
conversion, data format, and smoothing are not reflected in the output data.
An error occurs when attempting to save data that use the frequency offset function.
