Intrinsic Quality's chassis accommodates custom tester

To simplify the creation of a custom functional test system, the BarnOwl test chassis from Intrinsic Quality integrates many of the hardware elements common to most testers in a single chassis. The integrated solution can reduce design and procurement time, as well as development costs.
BarnOwl starts with a fixture kit that encloses tester resources. These resources include a single-board-computer–based test controller that provides both digital pins and analog test instrumentation. Internal 500-W power supplies source power to the DUTs through a programmable control that monitors both current and voltage. The user console of the BarnOwl features pass/fail lamps, a 4-line-by-20-character display, a thermal strip printer, and user input switches.
The chassis incorporates a set of 32 digital drivers, 32 digital sensors, 16 analog measurement channels, time and frequency measurement, multiple serial ports, and optically isolated I/O. What’s more, the BarnOwl has ample room to add application-specific circuitry.
Programming the test chassis is done through a serial connection to a PC. Once the Basic language test program is completed, the final version remains resident in the BarnOwl microcomputer’s flash memory.
The price of the BarnOwl test chassis starts at $5100, including development software. Intrinsic provides the BarnOwl as an unfinished, assembled kit or as a turnkey test solution. The company also provides turnkey in-circuit and functional test programs and fixtures.
