LTX

Xcerra Corporation (formerly LTX-Credence Corporation) was an American semiconductor Automatic Test Equipment (ATE) vendor, founded in 1976 in (co-founder) Sol Max's basement, later moving to the Balco building in Newton & GTE building 3 in Needham, then the KLH building on University Ave. in Westwood and currently headquartered on University Ave. in Norwood, Massachusetts (Greater Boston area).

The focus of the company was the design and development of ATE for the semiconductor marketplace, but it distinguished itself in the early days as a provider of functional and parametric testers for discrete component RF products. LTX offered test platforms capable of testing mixed signal (analog & digital) devices.
