Description

J-Testr is a highly compact ‘all-in-one’ modular functional test system controllable via Ethernet and JTAG. The small physical footprint and stowage features maximise the use of production space and also makes the J-Testr portable and easy to store.

J-Testr has both Ethernet and native JTAG communication interfaces so users can work with JTAG boundary scan tools and more conventional functional test software or scripting languages like Python. Driver examples for common Test Executives, scripting languages and JTAG test platforms are provided to allow users to choose their own preferred test software environment and operating system.

The J-Testr programming interface has been designed for flexibility, speed and simplicity. All internal functions are accessed via simple memory mapped 16-bit register sets, making any engineer with some micro-controller knowledge instantly at home.

Advanced debugging tools such as the ‘free’ open-source J-Debugr graphical debugging tool and low cost breakout cards help test engineers develop test code with ease, speed and confidence.

The J-Testr is designed with ‘test in mind’ and includes many advanced features to make testing both simple and safe. This includes the unique ‘J-Safe’ technology which provides high speed system shutdown in cases where the UUT may be at risk of damage.

Multiple UUT mounting options, including ‘bed of Nails’, allows the most suitable mechanical solution to be selected dependent on test volumes and budget
