TestStand 2019 introduced IO Configuration step types to control NI Modular Instruments including NI-SCOPE, NI-DCPower, NI-DMM and NI-FGEN using InstrumentStudio. You can initialize an IO session, apply an IO configuration to an existing IO session and close an existing IO session for NI Modular Instruments. You can also use the Sweep Loop step type to sweep on the instrument attributes specified by an IO session. The software required for these steps is listed below.
