PC-aided BJT tester revisited:
now with Windows software
The tester presented in this article is an update of the design published in our September 1993 issue. The ZN425 then used for the digital-to-analogue converter (DAC) is replaced by the currently more easily available AD557. Also, the 1993 DOS-version of the software has been replaced by a 32-bit program that runs only under Windows 95 or Windows 3.1 with a Win32S extension.
