In this paper, we use the embedded board with interface modules to implement a remote electronic measurement system which includes the power supply, signal generator and oscilloscope. This design uses an embedded board to replace a computer, since the embedded board has the advantages of being easily carried, a real-time operation, a low cost, and programmable. In addition, users can operate this measurement system with the help of the operating system and the TCP/IP modules to connect to the Internet. By using the on board operating system, our design provides the step by step function to help user operate, such as keying in the waveform parameters with the embedded board keyboard, providing the waveforms and then connecting the circuit to the embedded electronic measurement system. This design can also show the waveform measured by the embedded measurement system in the embedded board LCM (liquid crystal monitor). Because the file size of measured waveforms is very small, around 1KB, the prototype system shows that the main delay time to receive the measurement waveform at the server site from the client site is within 2.5 seconds. In the server, the observers can observe many waveforms from the different clients. If the client's waveform is error, the observer can also send the required waveforms to the client's embedded measurement system and input these waveforms to the testing circuits and re-observe the circuit measurement and help the user to debug. Finally, we compare our design with the popular data acquisition software, such as LabVIEW, LabWindows/CVI and VEE by showing the advantages and range of application differences
