ipTEST testers are top notch testers that test the static and dynamic parameters of discrete semiconductor like, diodes,transistors,MOSFETs,IGBTs,etc. Top players   like Infineon, ST, Onsemi are using them for their lab and FT production lines. They have adopted the modular designs for their testers. And by simply adding an additional module, a new test can be performed. It is pretty user-friendly and cost-efficient.
