JTAG signal conditional module links to VPC connection system

Based on the QuadPod architecture, the module has been specifically designed for connection into G20x or G14x 192 pin ‘QuadraPaddle’ connectors and is compatible with the VPC ‘pull thru’ system. By integrating the module, test system builders will greatly simplify their wiring task and, at the same time, retain the excellent signal integrity assured by the QuadPod’s active interface.

It features four independent JTAG Test Access Ports (TAPs) along with 16 static DIO channels and 64 dynamic DIOS channels. Each TAP can be programmed to operate through a range of voltage levels to suit various logic families.

JTAG/boundary-scan applications prepared using JTAG Technologies ProVision or ‘Classic’ software tools may be executed on this PXI platform with driver package

(now Marvin Test Solutions) ATEasy and a number of generic language compilers (e.g. .NET framework, C++ and VB).

The VPC adapters utilise standard QuadraPaddle connector modules, providing a wide variety of contact types. The connection between the PXI(e) instrument and receiver module is accomplished using either a passive printed circuit board, active signal condition module (as with the JT 2147/VPC) or flex circuit, with each providing optimum connectivity performance while reducing wiring cost.
