Hewlett Packard 4193A Impedence Meter. Internal oscillator provides test signals from 400kHz to 110MHz. Test signal is constant current between 10 microA, depending on impedance range (10 ohms-100 kohms, 5 ranges).Measures impedance magnitude from 10 mohms to 120 kohms and phase from -180.0 to +180.0 degrees. Other features include auto, hold, manual range control and a 3 1/2-digit display.
