ABSTRACT:
A testing apparatus tests the performance of an electronic device having an operation circuit for providing a useful output signal. A demodulator configured to provide a phase or frequency demodulated signal related to the output of the operation circuit is packaged with the operation circuit. The gain of the demodulator is controllable from outside the package. The testing apparatus analyses the demodulated signal and controls the gain of the demodulator.
