Hi @andy1 welcome to the forum! You are correct in that PathWave Test Automation is built on OpenTAP, however, OpenTAP itself is the complete sequencing engine, architecture and development environment and can be run and executed on it’s own with no Keysight licensing. PathWave Test Automation is generally used to build and debug tests in the R&D and DVT space, but for Manufacturing, most of our customers will take OpenTAP and build a custom operator UI or interface into existing UIs, as OpenTAP itself also has a complete execution UI. You can see an example of this in the videos here:
I’m sure others will be able to share their experiences as well.
