An analysis circuit for analysing the RF response of an RF circuit, includes a voltage controlled oscillator (), wherein a signal derived from voltage controlled oscillator output is applied as input to the RF circuit (). A first mixer () mixes the RF circuit output with a first mixer signal derived from the voltage controlled oscillator and a second mixer () mixes the RF circuit unit output with a second mixer signal derived from the voltage controlled oscillator, the first and second mixer signals being 90 degrees out of phase. The mixer output signals are processed to provide the analysis. This analysis circuit uses mixers to enable baseband digital signal processing of signals to enable a frequency response characteristic of the RF circuit to be obtained. The analysis circuit essentially operates in the manner of an IF demodulator circuit.
