Corelis has extended its broad line of ScanExpress boundary-scan hardware controllers and accessories with the addition of the ScanTAP IsoPod. The Corelis ScanTAP IsoPod is an add-on accessory that provides a complete electrical isolation barrier between the target system and the JTAG Test Access Port (TAP). It provides electrical isolation of the JTAG controller TAP signals from the unit under test and enhances the protection of the equipment against harsh electrical environments. The digital isolation offered by the ScanTAP IsoPod protects boundary-scan controller hardware from ground potential differences that are often present in production floors and in other industrial environments. The ground potential differences are especially harmful when using computer powered USB based test and measurement equipment where the computer and the target system are powered from different AC power lines sources in a noisy industrial environment.
While the Corelis boundary-scan controllers are highly robust and reliable, its use is often extended to harsh environment conditions and where isolation is required between the boundary-scan controller and the target system. While electrical isolation often limits the performance of the equipment on both sides of the isolator, the ScanTAP IsoPod was designed with high speed in mind, supporting test clocks with rates up to 45 MHz. The ScanTAP IsoPod is a drop in replacement for most of the Corelis TAP cables as it utilizes the standard 20 pin universal Corelis TAP connector pinout and it eliminates signal stress that might be caused by ground loops or voltage/ground potential mismatches in the test setup.
“The ScanTAP IsoPod is useful on the manufacturing line to prevent an entire line from going down when a controller is damaged and for development where untested targets pose the highest risk of damaging the target,” said George B. La Fever, CEO and President of Corelis. La Fever added, “The ScanTAP IsoPod is compatible with Corelis ScanExpress boundary-scan and functional test tools and most Corelis boundary-scan controllers. The current global economic condition is stressing our clients’ limited budgets and we are committed to develop products that reduce their test costs.”
Corelis, Inc., a subsidiary of Electronic Warfare Associates Inc., offers the industry’s broadest line of JTAG/boundary-scan software and hardware products that combine exceptional ease-of-use with advanced technical innovation and unmatched customer service. Soon after its inception in 1991, Corelis’ innovation in JTAG/Boundary-scan Test solutions ultimately resulted in acceptance as a major and preferred vendor of JTAG tools worldwide.
