Description
The XJTAG PXI-XJLink2 JTAG Controller is a professional-grade test solution that integrates seamlessly into PXI and CompactPCI® systems, bringing the power of XJTAG to modern automated test environments. Built on the robust XJLink2 architecture, this controller is designed to provide high-speed boundary-scan testing and in-system programming in both laboratory and production settings.
High-Performance JTAG Testing
The PXI-XJLink2 connects to up to four JTAG chains per UUT, making it ideal for testing complex designs or running parallel board-level diagnostics. With TCK frequencies up to 166 MHz and support for programmable voltage levels between 1.1 V and 3.3 V, it ensures reliable operation across a wide range of devices.
Seamless PXI Integration
Designed as a PXI/cPCI card (3U form factor), the PXI-XJLink2 integrates directly into standard PXI racks, minimizing electrical noise and ensuring compatibility with other test equipment. Engineers can take advantage of LabVIEW™ and TestStand™ integration through included Virtual Instruments, enabling smooth incorporation into automated workflows.
Flexible and Configurable Interface
The 20-way connector on the PXI-XJLink2 is fully configurable, allowing users to adapt pin-outs to their specific PCB requirements. This simplifies cabling and streamlines test setup. Spare pins can be reassigned as general-purpose I/O for additional tasks, such as resetting boards or performing fast Flash programming.
Built-In Measurement Tools
Every I/O pin includes a voltage meter (0–5 V) and a frequency counter (1 Hz–200 MHz) with selectable measurement periods. Combined with adjustable termination and auto-skew control, these features ensure maximum performance even when working with non-ideal signal conditions.
Scalable Test Solution
From a single development port to a multiport production setup, the PXI-XJLink2 provides a scalable and flexible JTAG test platform. Its self-contained licence system allows testing across multiple PXI racks or through a network server, eliminating the need to move licensed hardware.
With its combination of PXI compatibility, advanced measurement features, and robust test control, the XJTAG PXI-XJLink2 JTAG Controller is an indispensable tool for engineers who require reliable, high-speed, and flexible testing in demanding environments.
