The eXpert Tester has an unmatched pedigree. The proprietary ATVG test method is based on the test methods developed by Exatron's engineering team for military test applications in 1967-68 and has been improved in several generations since then. Each improvement has taken advantage of newest, enabling technologies, the latest of which are: SRAM-based FPGAs, state-of-the-art linear circuits, and Automatic Test Vector Generator (ATVG). The eXpert Tester will maintain its substantial growth ability to encompass emerging technologies due to the electrically-reconfigurable hardware. Without these new technologies the eXpert Tester would not be the innovative tester it is today.

1967	Testing Satellite Tracking Station modules (Philco Ford)
1969	Testing PC boards in F-15 Fighter Bomber (Kaiser Aerospace) The technology was then applied to a new application with the creation of the Develco Tester for Kaiser Aerospace.
1970	Testing PC boards for commercial applications Trendar Corporation was founded in 1970. The Trendar Tester was chosen "Electronic Test" magazine Product of the Year in 1972. Within 3 years the company was purchased by Fluke Engineering.
1974	Testing TTL circuits Exatron Inc. was formed in 1974 to manufacture and market the Model 500 Tester. Initial customer, National Semiconductor, purchased in excess of 30 of these testers.
1978	CMOS capability added Upgraded from the Model 500, the Model 510 had test capability both TTL and CMOS circuits with test times as low as 1 millisecond, test frequencies up to 7.00MHz and dynamic propagation delay testing to 25 nanoseconds. Customers included National Semiconductor and Signetics for their Hi Rel and off-shore testing needs.
1981	Partnerships with customers result in tester improvements Addressing the needs in the early 1980's for higher pin count digital testers, the Model 2800 featured real-time propagation delay testing and variable test frequencies to 20 MHz for TTL and memory devices to 28 pins. This generation was specifically developed for testing requirements off-shore for Signetics/Philips with assistance from their test engineering staff. The 2800 found acceptance also at Scientific Atlanta, Plessy Electro Products, and Allen Organ Company.
1987	PAL test capability expanded The PAL device market fueled improvements to the tester. Customers included AMD, Anthem Electronics, Arrow Electronics, Hamilton-Avnet, Kierluff, Marshall Industries, Schweber Electronics, Sun Microsystems, Western Micro Devices and Wyle Laboratories.
1989	Model 28000/38000 introduced Used to support Advanced Micro Devices' "TestPro" centers around the world. Combined both program and test through a relay multiplexer in one insertion.
1995	eXpert Tester beta-sites begun Initial beta-site activities were commenced at Atmel and other key accounts.
1996	Released to market
