Learn how to use a Source Measure Unit (SMU) with high-current arbitrary waveform capability for automotive power cycling testing. This app note describes a detailed procedure for performing Ford EMC-CS-2009.1 CI 230 Power Cycling Testing using the Keithley Series 2600B or Series 2650A System SourceMeter SMU instruments. Automotive power cycling tests require relatively high, precise currents, but relatively low frequency.  While this testing can be performed by using an arbitrary waveform generator with an amplifier, SMU's with arbitrary waveform capability eliminate the need for an amplifier and thus are well-suited for this application.
