The embodiment of the invention provides a wireless virtual oscilloscope and a power consumption dynamic management method thereof, and relates to the technical field of oscilloscopes. A terminal of the wireless virtual oscilloscope and an ARM microcontroller can select a USBOTG interface wired communication mode with high signal transmission stability and can also select a Wi-Fi communication mode with high flexibility, when the terminal of the wireless virtual oscilloscope and the ARM microcontroller select the Wi-Fi communication mode, miniaturization of the virtual oscilloscope can be achieved, and the terminal is completely separated from other parts of the virtual oscilloscope, so that the virtual oscilloscope is convenient to carry and easily used in the more severe remote measurement environment. The power consumption dynamic management method of the wireless virtual oscilloscope has the advantages that based on hardware functions, division is conducted, a function module not temporarily used in the wireless virtual oscilloscope is turned off or enters a low power consumption mode, so that when the wireless virtual oscilloscope uses different functions, the power consumption dynamic management is achieved, and the low power consumption design requirement of the wireless virtual oscilloscope is met better.
