“After the successful launch of the first IEEE 1149.1 controller for PXI in 1998, we are now again the first supplier of a complete tool suite of Boundary Scan PXI instrumentation,” Thomas Wenzel, managing director gladly announces. “The new products give us the opportunity to overcome the bottleneck created by the serial control of conventional JTAG I/O modules. The user is now able to implement the philosophy of Extended Boundary Scan for digital as well as mixed-signal applications in a higher quality.”

The family of Digital I/O modules includes the PXI 5296 with 96 channels and the PXI 52196 with 192 channels. All I/O channels are individually programmable as input, output, bi-directional, or tri-state. The 32 Channel Groups are voltage programmable between 1.8VDC and 5VDC. In addition to a high output current, each channel features a special protection circuitry to avoid interface damages due to high fault currents, and allows

Hot-Swap capability. Furthermore, a Differential I/O module PXI 5384 with 48 programmable channels is available.

The Mixed Signal I/O module PXI 5702 has two channels with 12 bit resolution for the generation or measurement of voltages. This module can also be used as digital pin driver. A safe signal handling is ensured by the programmability of driver currents (up to 350mA) and impedance.

The product family is completed by Power modules of the PXI 5120x series, which includes five different models (3VDC, 5VDC, 12VDC, 24VDC, 48VDC). All modules have two separate channels with 50W output power each, and are voltage and current programmable. Features, such as galvanic isolation, load rejection relays, U/I read back, and programmable current limitation are parts of the standard on these modules. In particular, for the support of the diagnostic Boundary Scan tests, all modules have an integrated U/I recorder per channel, synchronously operating to the BScan TCK clock. This provides, for example, easy diagnosis of Ground-Bounce phenomena.

The new PXI tool suite supports the PXI trigger bus and, therefore, can be synchronized to the actual Boundary Scan test procedure, controlled by the Boundary Scan controller PXI 1149.1. All modules are supported by the Integrated Boundary Scan Development Environment SYSTEM CASCON version 4.2 and higher, including ATPG, graphical Multi Mode Debugger, Pin Failure Diagnostics and the Boundary Scan programming language CASLAN.

For the integration in various test systems, test executives such as LabVIEW, LabWindows and TestStand can be utilized.
