Selecting a TestStand Sequence Template (Legacy)

Select a TestStand sequence template based on DUTs, signal type, and test items you want to check.

Sequence files are located in the following directory: C:\Program Files (x86)\National Instruments\LabVIEW version\ProjectTemplates\Source\Audio and Acoustics\Automation

The following table shows the signal types and test items supported by each sequence template.
