Abstract
The present general inventive concept is directed to a signal generation system, device, and method for meter testing, including a digital signal generator to generate an arbitrary digital test signal, a digital-to-analog converter to convert the arbitrary digital test signal to an analog test signal, a signal converter to convert the analog test signal to a differential pair of signals corresponding to the analog test signal, and a power signal generator including: an input module to receive the differential pair of signals; an amplifier to amplify the differential pair of test signals; and an output module to output an output differential pair of signals to a load, to feed back a proportional representation of the output differential pair of signals to the input module, and to receive the amplified differential pair of signals from the amplifier.
