| Abstract: | A technique for very low Q-factor impedance measurements, based on a lock-in amplifier as a vector voltmeter, is presented. Some practical details are discussed. The accuracy of the measurements has been studied by comparison, using a bridge method. As an application, the forward bias impedance of a variety of p-n junction is presented. |
