Embodiment 1

[0036] Embodiment 1. When the research and development personnel need to verify and detect the infrared signal sent by the infrared remote controller;

[0037] The infrared receiver receives the infrared signal sent by the infrared remote controller and transmits it to the FPGA, and the controller controls the infrared signal to be displayed on the display unit. In this way, the infrared signal can be automatically extracted and displayed intuitively.

Embodiment 2

[0038] Embodiment 2, when the research and development personnel need to detect or adjust the infrared remote control circuit according to the displayed infrared waveform;

[0039] Use the signal input channel of the oscilloscope to receive the external analog signal and send it to the analog-to-digital converter after being processed by the signal conditioning circuit, and then send the analog signal received by the signal input channel to the display unit for display through the FPGA and the control unit. It meets the needs of R&D personnel for circuit waveform detection of the infrared remote control device itself.

[0040] Such as figure 2 As shown, in embodiment three, when the research and development personnel need to detect or adjust the infrared remote control circuit according to the displayed infrared waveform; two display units can be used, the first display unit is used to display the waveform checked in the infrared remote control circuit, and the second The di...

The invention can not only meet the requirement of traditional waveform detection, but also can automatically extract and display the infrared signal.

Description

technical field [0001] The invention relates to the field of oscilloscopes, in particular to an infrared waveform detection method. Background technique [0002] The oscilloscope is an electronic measuring instrument with a wide range of uses. It is widely used in scientific research, teaching, engineering and other fields to detect the waveforms of various signals. The oscilloscope receives the detected analog signals through the information input channel, and A / After D conversion, the detected signal waveform will be displayed on the display through a series of adjustments. [0003] Infrared communication technology does not require physical connection, is easy to use and has low implementation cost, so it is widely used in small mobile devices to exchange data and control electrical equipment, such as between laptops, PDAs, mobile phones or between computers. Data exchange (personal network), remote control of TV, air conditioner, etc. [0004] Traditionally, semicondu...
