Accessed via the "Test..." button in XJLinkManager this enables you to run a diagnostic report on your XJlink2. When you first test a new circuit board that doesn't work this diagnostics test can give you confidence that your XJlink2 hardware ... http://blog.xjtag.com/2010/03/xjlink2-diagnostics/ We all pay close attention to the termination of high speed signals, especially clock signals. However in many of the designs I see this doesn't seem to have happened for the JTAG clock signal TCK. But TCK is a clock signal just like any other clock signal. Some people believe that ... http://blog.xjtag.com/2010/02/tck-termination/ One of the exciting new features of XJLink2 is the ability to measure a number of voltages. Via the 20-way XJlink2 connector you can measure up to 18 different voltages. This means supply rail voltages can be measured before (and during) JTAG testing, and analogue measurements are now simple to ... http://blog.xjtag.com/2010/02/voltage-measurements-with-xjlink2/ XJLink2 is the only JTAG interface that can accurately measure frequency. Why Measure Frequencies? Often in products oscillators are used, for instance in USB you require an oscillator to be within 100 ppm. With crystals this is seen as easy, but it can be a little harder than you expect. ... http://blog.xjtag.com/2010/01/xjlink2-frequency-measurement/ The new XJlink2 has a button and some LEDs, which aren't found on most JTAG interface devices. These are simply there to make life a little simpler on a crowded workbench. Once you have a project open in XJRunner you can start testing by just pressing the button ... http://blog.xjtag.com/2010/01/xjlink2-button-and-leds/ The new XJLink2 USB-to-JTAG interface is beginning to make its way out to our distributors and depending on where you are is, or shortly will be, available for trial and purchase.

It is intended to allow programmers the ability to integrate the XJTAG hardware into other test systems. The XJTAG installation includes example projects in C/C++ and C# demonstrating the use of the API. The C# ... http://blog.xjtag.com/2009/11/integrating-xjtag-with-other-test-systems-xjtag-api/ This series of posts covers how you can integrate XJTAG into your overall test system. This entry focuses on executing programs from within XJEase. The XJEase keyword SYSTEM is used to execute a system command or program. It accepts the command in the form of a string and returns the exit ... http://blog.xjtag.com/2009/11/integrating-xjtag-with-other-test-systems-system-calls-from-xjease/ In XJRunner, the Log File Viewer is a enhanced dialogue which allows you to view XJRunner's logged output without having to open an external text file viewer. If logging is enabled, one or more log files will be generated whenever tests are run. The Log File Viewer lists in the Explorer panel ... http://blog.xjtag.com/2009/11/xjrunner-log-file-viewer/
