Windows-on Visual Basic Oscilloscope Automatic Test Package

NH402, program-controlled regulator for the oscillograph, was designed in our laboratory for the need of NanHua device manufacturer in GuiZhou province several years ago, also can be used to adjust the digital frequency generator, signal generator, frequency analyzer and general voltage meter into expected precision. The test program for this device was design in ESI3ASIC under the platform of Dos firstly, no any clear windows at all and not convenient to handle. So we decided to make further reclamation on it under the windows platform. According the visual programming method under windows platform, such as VB, a new way to redesign the software kit of NH402 has been introduced in detail in my thesis, as well as using Microsoft Access to create both parameter and certification database of frequently-used oscillographs, which can be managed by the software kit. This software kit integrates several terrific features into itself, such as a user windows with clear and attractive style, powerful capability to arrange database and easy operation.
