Test equipment, method for operating a test equipment and computer program

A method for operating a test equipment, comprising:

• determining user-site compensation function comprising a compensation magnitude function and a compensation Hilbert phase function by using act user-site calibration unit, wherein said determining comprises:
• receiving and/or transmitting an actual electrical signal;
• measuring a magnitude characteristic of the electrical signal to generate a measured magnitude characteristic, wherein the magnitude characteristic is a basis for determination of the compensation Hilbert phase function;
• and
• determining a Hilbert phase characteristic of the electrical signal based on a Hilbert transformation of a function dependent on the measured magnitude characteristic.
