Abstract

The invention discloses an infrared remote control function signal generator which comprises a single chip, a keyboard, a reference voltage generating circuit and a waveform generator, wherein the infrared remote control function signal generator is characterized by also comprising a remote controller, an infrared receiver, a frequency band conversion controller, a summing circuit and a compression circuit; the remote controller transmits an infrared light signal to the infrared receiver after encoding and modulating the key information; the infrared receiver receives an infrared light signal emitted by the remote controller, converts the infrared light signal into an electric signal, demodulates, decodes, amplifies and outputs a control signal to the single chip; the keyboard outputs the control signal to the single chip; the single chip receives a control signal output by the infrared receiver and / or receives the control signal output by the keyboard, carries out processing conversion and outputs the signal to the frequency band conversion controller, the reference voltage generating circuit and the compression circuit, and the single chip also outputs a waveform selection control signal to the waveform generator.

Description

Technical field: [0001] The invention relates to a signal generator, in particular to an infrared remote control function signal generator. technical background: [0002] Function signal generators are widely used in electronic technology experiments, electronic product development, research, electronic equipment production debugging and system measurement, etc., and are widely used in schools, research institutes, electronic product manufacturers and electronic equipment maintenance units. [0003] When performing system measurements, it is not convenient to use ordinary signal generators if the distance between the devices is long. Because the measurement generally requires the coordination of a level meter or an oscilloscope, in order to reduce interference, the test line should not be too long, so it requires two people to cooperate, or one person to operate back and forth. Infrared remote control function signal generator is a kind of system test instrument. Its output signal...
