(using 7-Zip as example):
Unlike general-purpose oscilloscope software that may support a wide range of devices, 51Scope is typically designed to interface specifically with low-cost, USB-based data acquisition hardware or specific microcontroller development boards (often related to the 8051 architecture, hence the "51" in the name). Its primary function is to turn a PC into a basic oscilloscope or logic analyzer for educational and simple diagnostic purposes. http://www.51scope.cn/files/setup.rar
