Problems solved by technology

[0005] Usually commercial pulse generators, such as Tektronix AFG3102 arbitrary function generator, RIGOO's DG5352 signal generator, although there are certain differences in bandwidth, can generate sine waves, square waves, pulse waves, sawtooth waves, triangle waves, Sin Arbitrary waveforms including (x) / x, exponential growth and decay, Gaussian, Lorentz, haversine, DC, noise, etc., so the price is relatively expensive

Abstract

The invention relates to a tunable pulse signal generator capable of driving an LED. The tunable pulse signal generator comprises a power supply module, a field programmable gate array, a programmable potentiometer, a DC-DC converter and a level converter. The field programmable gate array is used for generating pulse signals and a control instruction; the programmable potentiometer is used for adjusting resistance according to the control instruction; the DC-DC converter is used for converting the power supply voltage input by the power supply module, and adjusting voltage output according to the resistance of the programmable potentiometer; and the level converter is used for carrying out level switching on the pulse signals according to the adjustable voltage output by the DC-DC converter. The tunable pulse signal generator capable of driving the LED can realize the pulse signal generator, the parameters of which are accurately adjustable.

Description

technical field [0001] The present invention generally relates to a pulse signal generator, in particular to a tunable pulse signal generator for driving LEDs. Background technique [0002] Various photoelectric conversion devices such as photomultiplier tubes and silicon photodetectors can convert optical signals into electrical signals and at the same time realize the multiplication and amplification of photoelectric signals. They are widely used in scientific research, industrial production, environmental monitoring and medical equipment and other fields. . Different applications have different requirements for the performance accuracy of such photoelectric conversion devices, so it is very important to perform performance calibration effectively. By performing performance calibration on different photoelectric conversion devices, suitable devices can be selected for professional testing. At present, the performance calibration of photoelectric conversion devices such as...
