ABSTRACT:
A programmable data acquisition system including a plurality of input signal channels for receiving a respective input signal during a normal mode of operation is provided. Individual test circuits are used for selecting respective ones of the plurality of channels to receive predetermined reference signals during a test mode of operation while uninterruptedly providing the normal mode of operation in any remaining unselected channels in the data acquisition system. An analog-to-digital (A/D) converter system, such as delta-sigma modulators and decimation filters having a selectable decimation ratio, allows for supplying quantized electrical signals at a predetermined rate. The A/D converter is responsive to any signals carried in the plurality of signal channels as selected by the individual test circuits. A control unit allows for supplying respective control signals to the test circuits and to the converter system. The data acquisition system can further include at least one feedback generating circuit for generating a measurement signal supplied to a respective one of the signal channels. This allows the data acquisition system for interfacing with a zero-flux current sensor.
