Abstract:
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.
