JTAG Technologies, a provider of boundary-scan tools, has announced a graphical software tool that supports the new SCANSTA476 analog voltage monitor from National Semiconductor Corp. STA476 Utility program works with an evaluation board from National Semiconductor to perform and report DC measurements on eight analog/mixed-signal input channels.
 
Measurement of mixed-signal levels can be a beneficial troubleshooting technique during product development, environmental screening, functional testing and in-field service to verify power supply and reference voltages.
The technique can be used to perform health monitoring and prognostic functions while in operation, via an embedded boundary-scan structure.


 

The GUI allows selection of any of the eight analog inputs on the evaluation board. Measurements can then be conducted on the selected channel(s) using a preselected controller to initiate the test and access the results over a standard 1149.1 boundary-scan interface.
 
The utility program is available free-of-charge for customers at the Customer
Service Area of the JTAG Technologies website.
