I am using a PXI-6704 to generate up to sixteen 4-20 mA signal outputs and it works great as a sourcing output. Is there a way to use the PXI-6704 as a current “simulator,” which would require an external power supply? For example, most 4-20 mA calibrator devices have both a “sourcing” and “simulate” mode. We test display and control systems that uses many 2-wire mA output sensors and it would be nice to use the PXI-6704 without rewiring the system to delete the external power supply.
