LTX-Credence
The LTX / Credence Fusion MX is a tester system manufactured by LTX/Credence. The LTX / Credence Fusion MX includes submodules such as SBA, OVI, HVVI, DIGHSB, FX2, TMBDFX, VI16B, and SWG.[1]

The Fusion MX supports a range of instrument options, including an SBA, OVI, HVVI, DIGHSB, FX2, TMBDFX, VI16B, and SWG.[1]
Automatic test equipment for semiconductors uses a test head that makes electrical contact with the device under test and a system controller that executes test programs to apply stimuli and capture responses.
The Fusion MX sits in the final test stage of semiconductor manufacturing, after wafer probing and packaging, where each packaged device is electrically tested to verify functionality and performance.
Semiconductor test equipment operates in the production flow between the assembly line and the shipping or burn-in stages, serving as a quality checkpoint.
The Fusion MX is used for testing analog, mixed-signal, and digital semiconductor devices.
Typical applications include testing power management integrated circuits, audio amplifiers, data converters, and other linear or mixed-signal components.
