Design Of Digital Oscilloscopes Help System Based On Android

An oscilloscope is the equipment which used in various fields of measuring engineering. Using an oscilloscope, you can measure signal’s current and voltage. And you can observe the waveform of a signal. Android-based Tablet Oscilloscope is a portable oscilloscope mounted on tablet. Because Android-based Tablet Oscilloscope using the hardware of a Tablet as its main body, its weight is very light and its size is very small. For the staffs who always need to go out doing measuring operations and need to take a n oscilloscope, Tablet Oscilloscope is portable and can provide maximum convenience to the user.Digital oscilloscopes have a lot of functio ns. Depending on the different type of digital oscilloscopes and different places of using, the method of using is not exactly the same. For the users wh o use the oscilloscopes the first time, it is hard to know how to use the oscilloscopes. Each oscillosc ope supports the instruction to help users learn how to use the oscilloscope. But the instruction is not easy to carry and view. For the Android-based Tablet Oscilloscope, We can design a help system for the oscilloscope software. Designing a help system c an avoid using the instruction. Because the help system is embedded in the Tablet oscilloscope software program, the help system and software program are linked more closely. The human-computer interaction becomes easier.The paper designs a help system for the Android-based Tablet digital oscilloscope software program. There are text and picture in the help system as instruction. And there are also animation s in the system. Using the help system, people can know the instructions of the digital oscilloscope software program more easily and the system provides convenience to users. At the same time, the paper designs the functions of trigger, MATH and digital filter for the oscilloscope software program. And these designs combine with help system using a help bar and become a whole unity.
