US Patent 7343538 Programmable multi-function module for automatic test equipment systems

A programmable source/measurement module for automatic test equipment is disclosed. A high resolution low frequency source, high resolution low frequency measurement capability, low resolution high frequency source, and a low resolution high frequency measurement capability are provided in a single module. The module comprises an input/output switch matrix selectively coupled to a low frequency filter block and a high frequency filter block. Each filter block may be used for either source or measurement. The filter blocks are selectively coupled to a plurality of analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). The ADCs and DACs are coupled to a digital interface.
