Embodiment Construction

[0017] see figure 1 , a control device for a handheld digital oscilloscope, including a dual-channel input device 1, an AD module 2, an AD module 3, a keyboard input device 4, an FPGA module 5, an LCD display device 6, an EXT trigger input device 7, and a USB interface 8. The dual-channel input device 1 is connected to the AD module 2, and the AD module 2 is connected to the FPGA module 5, and the input device connected to the FPGA module 5 is a keyboard input device 4 and an EXT trigger input device 7, and the output device connected to the FPGA module 5 is LCD display device 6 and USB interface 8 .

[0018] The signal to be tested is converted from the dual-channel input device 1 to the DC bias conditioning of the operational amplifier and relay, and then converted into a signal that can be processed by the AD module 2 sampling circuit, and then sent to the AD module 2 circuit. The conversion of analog signals to digital signals is completed under the control of the system...

Abstract

The invention discloses a control device for a handheld digital oscilloscope. The control device comprises a double-channel input device, an analog-to-digital (AD) module, a field programmable gate array (FPGA) module, a keyboard input device, a liquid crystal display (LCD) display device, an extension (EXT) trigger input device and a universal serial bus (SUB) interface, wherein the double-channel input device is connected with the AD module, the AD module is connected with the FPGA module, and the FPGA module is connected with the keyboard input device and the EXT trigger input device which server as input devices, and is connected with the LCD display device and the USB interface which serve as output devices. The control device is small and exquisite, is convenient to carry, and has low power and low energy consumption.

Description

technical field [0001] The invention belongs to the field of electronic technology and measurement and control technology, and relates to a control device for a hand-held digital oscilloscope. Background technique [0002] With the continuous development of electronic testing technology, testing technology is developing in the direction of automation, intelligence and digitization. With its superior performance, digital storage oscilloscopes are gradually replacing traditional analog oscilloscopes. However, due to the large size of the desktop oscilloscope, it is not convenient to carry it for on-site testing and field work. The appearance of the handheld oscilloscope makes up for this shortcoming. It occupies a place in the field of oscilloscopes by virtue of its small size, light weight, battery power supply, and portability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control device related to a handhe...
