Short-distance operable digital oscilloscope

Abstract

The invention discloses a short-distance operable digital oscilloscope. A wireless data interaction channel is innovatively arranged on the basis of the conventional digital oscilloscope, so that the digital oscilloscope can be wirelessly connected with any one intelligent handheld equipment, and operations such as sampled data processing, image display and operation and human-computer interaction of the conventional digital oscilloscope can be transferred to the intelligent handheld equipment. By using the strong operation capacity and good operation and portability characteristics of a high-speed multi-core CPU (Central Processing Unit), GPU (Graphic Processing Unit) and a touch liquid crystal screen of the intelligent handheld equipment, not only the sampled data processing capacity, the image display capacity and the human-computer interaction capacity of the digital oscilloscope can be obviously enhanced, but also the digital oscilloscope has the short-distance operation capacity. The short-distance operable digital oscilloscope is more suitable for field testing under hard and dangerous environments and high sensitivity requirements.

Description

technical field [0001] The invention belongs to the technical field of digital oscilloscopes, and more specifically relates to a digital oscilloscope capable of short-range operation. Background technique [0002] With the continuous deepening of human research in the field of digital signals, the application environment of digital acquisition systems is becoming more and more complex. As a representative of high-speed digital acquisition, digital oscilloscope technology has developed rapidly, and the core indicators of oscilloscopes such as bandwidth, sampling rate and storage depth have been continuously improved. However, most of the existing digital oscilloscopes use ADC+FPGA (Field Programmable Gate Array)+DSP (Digital Signal Processor) as the core structure. The DSP computing power of the device is limited, and there is not enough resources to support the operation of a small operating system, resulting in weak data processing and image display capabilities of the dig...

However, most of the existing digital oscilloscopes use ADC+FPGA (Field Programmable Gate Array)+DSP (Digital Signal Processor) as the core structure. The DSP computing power of the device is limited, and there is not enough resources to support the operation of a small operating system, resulting in weak data processing and image display capabilities of the digital oscilloscope; at the same time, in the face of increasingly complex test requirements, traditional digital oscilloscope panels The operation method carried out on the computer not only seems to be stretched, but also cannot adapt to the on-site test under certain difficult, dangerous and high-sensitivity requirements, resulting in poor human-computer interaction and portability adaptability of the digital oscilloscope.
