ABSTRACT:
Apparatus for measuring the A.C. characteristics of a circuit element under test maintains a stable D.C. bias voltage across the component under test by sensing the difference between the output voltage of the D.C. bias voltage source and the voltage drop across the circuit element under test, to control the D.C. bias voltage applied and to compensate for variable voltage drops in the measurement circuit. The apparatus compensates both for the fixed resistance in the circuit and for the variable resistance due to changing the range resistor.
