J-Testr

J-Testr

Highly compact ‘all-in-one’ JTAG  / Ethernet controlled modular functional test system.

The J-Testr is a highly configurable, compact functional test unit that provides a complete power, thermal and stimulation environment to the users’ Unit Under Test (UUT). The system can be setup and entirely controlled by JTAG, for example using XJTAG; or, driven by Ethernet (e.g. with ATEasy test software or Python); or both, e.g. drive with JTAG and monitor over Ethernet.

The built in load testing (up to 80W), timer card (75Mhz frequencies and pulses to 5ns resolution response), power supply (programmable ramping, monitoring, low noise, sequencing), analogue (16 bit, DAC / ADC, programmable external mux), digital I/O, communicatons (RS422/485, CAN, ARINC429) plus ability to add bespoke test electronics means that the system can replace much larger, bulkier and more costly test systems while providing a straightforward environment for fast test development.

More specialist measurement of RF power & frequency; optical sensing for LEDs; in-system programming and high-voltage switching provide even more test, manufacturing and programming capabilities.

Physical integration with the UUT is achieved with a simple to design interposer card (with 'J-Mount' mechanical mounting system if required), or, the 'J-Testr+' range of Bed-of-Nails fixtures.
