XJTAG PXI modules — PXI to JTAG interface
The PXI and PXI XJLink2 modules allow the integration of XJTAG into PXI-based test systems. All XJTAG PXI modules are easily integrated with LabVIEWTM with a full set of Virtual Instruments (VIs) included.
Example of connectors to connect to the PXI front module: Manufacturer: 3m (refs. 10320-3210-000 and 10120-6000EL)
Key Benefits
- Standard PXI interface: ideal for lab and production work.
- Modular, scalable solution.
- Self-contained licence allow you to run XJTAG from a standalone PXI rack.
- Re-configurable unit for multiple UUTs saving costs.
- Easy integration with NI's LabVIEW*.

PXI/cPCI solution
All XJTAG PXI modules are CompactPCI® compatible so they can be used in any cPCI or PXI-based test system.*
Configurable JTAG interface
Only one simple cable assembly is required to connect to your target board — no extra adapters needed. The 20-way connectors are configurable to match the connector pinout on the PCB. The ability to change the pinmap for the JTAG signals simplifies the process of connecting your XJTAG test system to the Unit Under Test.
Integration
The standard .NET and COM interfaces allow you to integrate XJTAG testing with test executives such as NI LabVIEWTM, LabWindowsTM/CVI, with ATE machines, or a bespoke application written in languages such as Visual Basic® and C#®. XJTAG provides coding examples for LabVIEW, LabWindows, C#, C++, and Visual Basic.
Flexible & scalable
From a single port system for development to multiport test and programming systems in production, the PXI and PXI XJLink2 modules provide a flexible, scalable JTAG solution.
With self-contained licences, all XJTAG hardware provides flexibility as no network connection is required for the test system to run.
Advanced connectivity
All XJTAG PXI modules have variable signal termination, so they can handle boards both with and without signal termination. The advanced auto-skew control enables you to get the maximum frequency out of your JTAG chain and cable.
