Agilent Technologies has introduced the M9186A PXI isolated single-channel voltage/current source, a modular voltage-current source for use in automotive electronics test applications. The modular PXI-based solution enables testers to generate a voltage and measurement of the resultant current, or generate a current and measurement of the resultant voltage. The source comes with SENSE input to supply accurate voltage to the device under test (DUT). The module also offers a safety interlock feature to protect the DUT from potential damage from high voltages. Agilent will include sample codes that end-users can easily modify. This simplifies the process of integrating the module into a measurement system and reduces the amount of time it takes to complete complex tasks.
