摘要： A method and apparatus for generating an arbitrary current waveform for use in characterizing power supply impedance for power delivery networks are provided. The method begins by providing an arbitrary waveform as an input to a test circuit. The current and voltage at an output of a device under test in then examined A frequency is then swept through a pre-determined range; and the frequency of the arbitrary voltage waveform is changed to match a predetermined frequency and impedance point.

摘要： A measurement instrument includes selectable channels for simultaneously measuring current on a power rail/load of a device under test. Multiplexor circuitry can be controlled to select power rails/loads for measurement and to couple unselected power rails to bypass the measurement circuitry. Active loads are provided in the measurement circuitry to compensate for loading by the measurement circuitry. The active loads cause current on a source side of a selected power rail/load to match current measured on a load side of the selected power rail/load during power measurements.
