In using the JT 2147/DAK, test system builders will greatly simplify their wiring tasks and, at the same time, retain the excellent signal integrity assured by the QuadPod’s active interface. The JT2147/DAK features four independent JTAG Test Access Ports (TAPs) along with 16 user-assigned DIO 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 packages that are available for NI LabView, TestStand and LabWindows alongside Geotest ATEasy and a number of generic language compilers (e.g. .NET framework, C++ and VB).
DAK adapters use standard MAC Panel series connector modules, providing a wide variety of contact types. The connection between the PXI instrument and receiver module is accomplished using either a passive printed circuit board, active signal conditioning module (as with the JT 2147/DAK) or flex circuit, with each providing optimum connectivity performance while reducing wiring cost.
