I'll add that LabVIEW isn't only used for test and measurement, but also to control real systems. My company builds high performance motor drives, solar panel inverters, energy storage systems, hybrid-electric vehicle emulators, aerospace flight controls, and many other products that require deterministic and high fidelity control systems. With LabVIEW we can write code that executes every second (PC), every millisecond (real-time), or every microsecond (FPGA) without worrying so much about low-level compiler optimizations, HDL timing constraints, and many other problems that come up with non-LabVIEW embedded systems.

Hoovah,
A few abbreviations you used I'm not familiar with. What are you referring to with DV, PV, and ED testing?

Here at Alpha Technologies and at our subsidiary Outback Power, we use LabVIEW in production test, qualification, and R&D.

Danm those TLAs. Three letter aconims. Worse,are those XTLA (extended three letter acronyms) and DXTLAs (double extended TLAs) Abbriviated TLAs are "AT"s
Design Verification
Production Verification
Engineering design? (Soft front panels)

Thanks.
But technically they are tLA. two Letter Acronyms. (never heard of that one before, but since two and three both begin with a "t" .....

ED - Engineering Development
Before any real testing is done, mostly debug level, troubleshooting tests to make sure the basics of it are working. Tested with hand built parts, usually using similar components as the end product but nothing is set in stone on the design. Usually no report generation is done other than a traveler piece of paper, on the UUT stating it works.
DV - Design Verification (and/or Validation)
Hand built parts with what is expected to be a product that is the same dimensions and using the same components as the final product. The product is basically the same as the final ones, but the process of building them isn't refined. The testing can be quite through and takes several months to a year to complete.
PV - Product (Production or Process) Validation
Parts built using the final real process. Usually involving robots, or finalized work instructions specifying every thing about the build including screw torque amounts. The majority of the testing DV did isn't done here because the design shouldn't change from DV to PV, but the process has so other tests might be added.
Usually there are multiple DVs depending on how much the design changes. Some DVs are to cut cost and are expected, assuming the savings is worth the time and effort to perform another validation. Some re-testing isn't required based on what was changed too. There is hopefully only one PV, but if something major changes like the entire line moves buildings, or tooling changes take place, then multiple PVs maybe required. For instance if a relay is replaced with a cheaper version you shouldn't need to perform leak testing again which is usually part of a DV. But if the sealant between covers is changed a leak check will probably be necessary.

Those are Abbriviated TLAs just call them ATs
