ABSTRACT:
In the precision source disclosed herein, a reference waveform and a correction waveform are combined and fed to an output amplifier which supplies an output waveform to a load, e.g., a wattmeter under test. The reference and correction waveforms are generated by digital-to-analog conversion of values stored in respective data tables. The output waveform is then combined with the reference waveform to obtain an error signal which is then digitized and utilized to update the data table from which the correction waveform is generated.
