The Scanflex Boundary Scan controller (SFX-controller) family from Goepel electronic is named SFX/PXI1149/CX-(x) and includes six models in different performance classes. The increasing number of highly complex PXI applications with Mass Interconnect Interfaces is challenging the integration ability of instruments. The SFX-controllers are designed for this task because of their compact and flexible interfaces. They are the first controllers having completely integrated the normally separate TAP transceivers in the 1 Slot/3U controllers. The typically hard to mount external pods can be omitted, particularly for Short Wire Adaptations. Additionally, the wiring effort for different Interface Test Adapter (ITA), for example, from Virginia Panel or Mac Panel, can be minimised by exchangeable Connector Paddle Cards (Conpac).
The controller series includes a 2 TAP and a 4 TAP version, available in three performance classes A, B and C. The models differ in the upper TCK frequency limit (maximum of 20, 50, or 80 MHz) as well as the level of implementation of the enhanced Space II chip set for high performance scan operations. The integrated Fastscale technology allows an upgrade of the controller’s performance class ‚on the fly‘, without intricate mounting of additional hardware. Furthermore, as standard features all controllers include Adycs II to compensate for signal path delays, and Hyscan for dynamic splitting of serial TAP vectors and parallel I/O vectors. All TAPs provide programmable input and output voltage as well as programmable input and output impedance, programmable TCK frequency, programmable delay compensation, read-back of the output signals and a relay controlled power signal. Resources such as 32 dynamic I/O, two analogue I/O channels, three static I/O, and trigger lines are standard features.
The SFX-controller is fully supported in the Boundary Scan Software System Cascon from version 4.3.1 onwards. Based on its API functions (Application Programming Interface), software plug-in modules are available for comfortable system integration using tools such as NI LabView, NI LabWindows and NI TestStand, among others.
