Abstract

A measurement apparatus comprising a first terminal to receive an input signal of a circuit under test; a second terminal to receive an output signal of the circuit under test. A first and second phase splitter configured to generate a first and second phase signal, Iand I, and a first and second quadrature signal, Qand Q. A first and second multiplexer, each coupled to the first terminal and the second terminal and configured to alternately pass the input and output signals of the circuit under test to the inputs of the first and second phase splitters. A double-quadrature mixer having four inputs configured to receive I, Q, I, and Q, and an output. A calculation unit to determine one or both of a phase shift of the circuit under test and/or a gain of the circuit under test based on the output of the double-quadrature mixer.
