This application note provides an easy, step-by-step approach for measuring and plotting several characteristics of a DC-DC converter using Keysight’s 34970A/72A DAQs with BenchVue software. The DAQ includes a DMM and relays, and can make measurements at speeds of up to 250 readings/second at selected measurement points.
While one example is provided, the concepts described are applicable to a wide range of devices under test (DUTs) for which multiple measurements need to be made.
