Title: Intelligentized equipment of much function that added to common stimulant oscillometer
Abstract:
It is a well established fact that the oscilloscope has made great progress. With digital technology ,an oscilloscope has become an intelligent instrument with functions: waveform display ,parameter measure ,detecting ,analyze ,storage, and so on. But at the same time ,it is not an easy task to build a system of oscilloscope because of many intractable problems. The article involves in resolving following questions.
This system is divided into the five greatest parts totally: The lord controls the mold piece, person's machine connects to connect, signal importation letter way, the signal replies the mold piece now, data the correspondence connects. According to actual environment, this device satisfy then conduct and actions common imitate show a machine additional part, and then can circulate independently. Can collect the 10 kHz. following various period and the non- period low frequency signals, have the au to trigger the sample, move to sample 2 kinds of methods. When the system is placed in the automatic document, having the cathode signal importation to start to sample the process namely; When the system is placed in to move the document, can start sample the process through the " start" button. Sample the signal of empress since can be save in the RAM of have the electricity protection function to lie in the quality, and then send out the PC machine, keep with the disk document form. The RAM capacity is a 8 KB. The signal reply now for the sake of easy to analysis processing, request to sample behind of signal can ask for help from to imitate to show a CRT of machine and the following 3 kinds of square Fix manifestation, divide page manifestation, slip to move the manifestation. The data processing drive signal collect behind can in order to the Chinese characters form the manifestation was sample in showing a machine CRT the value of the single pulse form, all be worth and the vein breadth, the period of a form of period, value. The system still has to permit the wrong ability basically.
