Abstract
A tester for a circuit path includes a voltage controlled oscillator (VCO) for generating a controllable frequency oscillating test signal and having a controllable amplitude defined between first and second voltages, a multiplexer for selectively connecting one of the oscillating test signal, the first voltage, and the second voltage to the circuit path, and a selector for selectively connecting the multiplexer to the circuit path. Moreover, at least one of the first and second voltages may be controllable so that the VCO generates the oscillating test signal to selectively have one of an amplitude greater than, less than, and equal to an amplitude of an output of the circuit path. The circuit path may include a plurality of electronic circuit devices connected together.
