Abstract

The present invention proposes a wireless transmission type digital oscilloscope device, including: a frequency meter module, a multimeter module, an oscilloscope module, an embedded CPU module and a wireless transmission module; the radio frequency front-end circuit includes a voltage doubling circuit, a voltage stabilizing circuit, and a reset circuit , clock circuit, modulation circuit and demodulation circuit to generate power, clock, data and reset signals required by the digital baseband circuit. The digital baseband circuit includes a data synchronization module, a data decoding module, a main control module, a data storage module, and a data decoding module And the clock generation module analyzes the demodulated data, completes the data encoding according to the instruction, and modulates the antenna. The digital baseband circuit sends out the data signal to be sent through the modulation circuit of the RF front-end circuit. The invention utilizes the radio frequency signal through magnetic field coupling or electromagnetic wave transmission to realize non-contact information transmission. Since the frequency reaches the microwave band, the anti-interference performance is stronger and the transmission distance is longer.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a digital oscilloscope device. Background technique [0002] Digital oscilloscopes are generally used for on-site testing and maintenance services. When testing or maintenance personnel diagnose equipment faults on site, they often need to save the test data and analyze and compare the data to quickly locate the fault. However, this method of on-site testing requires professional testing or maintenance personnel to conduct on-site equipment, and the efficiency of fault diagnosis is closely related to the ability of testing or maintenance personnel, so the efficiency is relatively low. [0003] Domestic existing digital oscilloscopes generally support data storage and wired transmission functions. The equipment testers save the test data on site, and then transmit the test results to the remote computer by cable for use by professional testers or maintenance personnel, and can ev...
