The UPT2-4 and UPT2-8 Port Testers are
production testers designed to test functionality with
root and hub ports of USB 2.0-capable
motherboards, PCs and hubs according to the USB
2.0/1.1 specifications. They provide a quick pass/fail
indication for the unit under test and are capable of
testing up to eight ports in a single setup. The
UPT2 systems include the test fixture pictured here
(hardware) and a DOS application program
(software) that controls the test process.
