Notes about the STDF file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The STDF file type is primarily associated with 'SEDana' by Salland Engineering. Standard Test Data Format is a typical file format used for storing measurement data generated by Automatic Tester Equipment. The format is developed by Teradyne and is now commonly used as a standard for tester data. Most of the testers from Credence, Agilent, LTX and others can generate this format.
