This eagle hunts for flaws, not paws. Eagle Test Systems makes automated test equipment (ATE) systems used to test analog, mixed-signal (analog with digital), and radio-frequency (RF) semiconductor devices as they are being manufactured. Customers include Infineon Technologies, International Rectifier, Intersil, National Semiconductor, and Texas Instruments (around 31% of sales). Eagle Test Systems gets about two-thirds of sales outside the US, primarily in Malaysia. In 2008 rival Teradyne agreed to buy the company for about $250 million, net of cash.
