Along with the development of the oscilloscope technology and computer technology, signal detection and analysis of the precision demand is higher and higher, the general oscilloscope relatively cumbersome to use not convenient and accuracy is not high, and modern computers are usually has to use flexible and convenient usb interface, thus the high-performance virtual oscilloscope based on usb interface will appear in the measurement industry.
USB oscilloscope, adapter is the core of USB oscilloscope, mainly for signal measurement, PC data processing analysis and data display with the computer monitor. The components of the adapter are preamplifier and attenuator, A/D converter, USB interface, etc., the measured signal is actually preliminary processing in the adapter, through the USB interface to send data to PC, PC running software processing and analysis of the received data, and then the results are displayed on the computer screen. The appearance of the oscilloscope displayed on the PC and the general oscilloscope is much the same, all the panel operation and the general oscilloscope is no different, on the PC is through the graphical interface and related buttons to achieve, control with the mouse can.The large display of PC can be supplemented by the perfect graphical user interface on the display signal waveform. At the same time, due to the intervention of PC, the measuring precision of oscilloscope is also improved, because it has become one of the mainstream of the new generation of oscilloscope.
