J-Testr+ GTI

The J-Testr+ GTI test system is a complete functional circuit test system in a compact, ready to use desktop format. Measuring 465mm x 500mm in standard form and with all Unit Under Test (UUT) surfaces ESD safe it can fit into any production process. The  J-Testr+ GTI utilises a unique system of Exchangeable Units , making it a test solution configurable for all levels of volume from prototype to full production. 

The J-Testr+ GTI includes options such as ; RF and integrated oscilloscope , LED analyser, high speed programming and JTAG and as standard incorporates J-Safe our advanced defence against board level faults offering a system-wide protection scheme.

J-Testr GTI 'Bed of Nails' Customisation Service


GTI - Test Straight Out Of The Box

​With the Generic Test Interposer (GTI) the system is ready to use with no customisation required. All stimulation and measurement signals are readily available whether automatically plugging with a mass inter-connect system (e.g. Pylon) or direct plugging with standard pitch ribbon cable.  Both Ethernet and native JTAG communication interfaces are supported and the simple register based software interface allows users to choose their own  test software environment and operating system.

Exchangeable Unit For Easy & Rapid Changeover

​The connector pin-outs on the Exchangeable Units are identical for low cost direct plugging or mass inter-connect options, allowing simple transition between interface types. 
All Exchangable Units use standard pin and pitch interfaces supporting all stimulation and measurement signal types, keeping connection types the same and allowing the use of standard cables.
Flexible ‘Pass-Thru’ wiring enables easy routing of low or high speed signals between the UUT and additional equipment, internal or external to the J-Testr+ GTI system.


Prototype Test Made Simple

​A unique ‘Prototype Exchangeable Unit’ allows the test system to be used immediately upon receiving the first/prototype UUT with NO tooling. This allows test developers, or even R+D teams, to utilise the test system from a very early stage in the product development cycle. Test development and design verification can be done before committing to ‘Bed of Nails’ tooling, allowing developed test code/circuitry to be easily reused and passed forward to the final production test, saving significant time and resource. 
Using our J-Mount, the UUT can be held securely with quick and easy insertion, lock and release, without damage to components or solder joints.
