5. Instrument Control

The Instrument Control settings section of the Arbitrary Waveform Generator allows the user to select which device they are using to output a signal and if they’d like to run continuously, or once. This section also holds stop button and a link to the help section for the Function Generator in the NI ELVISmx help.

The device drop down selection box allows a user to select any myDAQ or ELVIS unit that is connected to the system.  The device list, which includes the device numbers, is pulled from the devices and interfaces that can be seen in Measurement and Automation Explorer.  To test or rename each device, see the Configuring and Testing your myDAQ in Measurement and Automation Explorer page.
