Abstract

This handheld Scopemeter is a portable tool for waveform measurement. In contrast with analog oscilloscope, desktop digital oscilloscope or digital multimeter, it is one of the best test toos for use in teaching or field.

It uses a high speed AD sampler to convert the input analog signal into digital signal and displays the signal on a 128 x 64 LCD after processing the signal through a high-speed CPU.

It uses a high speed comparator to get a good edge trigger for a steady display, which is good for observation.

Its multimeter part uses a dedicated, 6000-count chip, which can provide a higher precision.

the scopemeter is equipped with a large capacity lithium battery, which an provide about 10 hours of use after it is fully charged.
