A test equipment has a signal input/signal output and a use-site calibration unit for determining a user-site compensation function. The user-site compensation function has a compensation magnitude function and a compensation Hilbert phase function. The calibration unit has a level meter and a calculator. The level meter is configured to measure a magnitude characteristic of the electrical signal, the magnitude characteristic being the basis for the determination of the compensation Hilbert phase function. The calculator is configured to determine a Hilbert phase characteristic of the electrical signal based on a Hilbert transformation of a function dependent on the measured magnitude characteristic and to determine the compensation Hilbert phase function on the basis of the Hilbert phase characteristic.
