Abstract

The invention relates to the technical field of CELL testing machines, in particular to a CELL testing machine capable of generating arbitrary waveforms based on an FPGA (Field Programmable Gate Array) technology, which comprises an mcu main control board, and is characterized in that the right side of the mcu main control board is electrically connected with a waveform generating mechanism through a wire; and the waveform generation mechanism comprises an FPGA module, a digital-to-analog conversion module, a low-pass filter circuit, a program control amplification circuit, an analog-to-digital conversion module, a key input module, a display module and a waveform memory. According to the invention, the problems that a CELL test machine required at present cannot generate any waveform according to the requirements of a user and the intelligent degree is low can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of cell testing machines, in particular to a cell testing machine for generating arbitrary waveforms based on FPGA technology. Background technique [0002] At present, the CELL testers on the market mainly use direct digital synthesis technology. Direct digital frequency synthesis technology is an advanced all-digital frequency synthesis technology. It has a variety of digital modulation capabilities (such as phase modulation, frequency modulation, amplitude modulation and I / Q quadrature modulation, etc.), compared with traditional frequency synthesizers, it has the advantages of low cost, low power consumption, high resolution and fast conversion time. [0003] The currently required CELL testing machine cannot generate arbitrary waveforms according to user requirements, and the degree of intelligence is low. [0004] To sum up, the present invention provides a CELL testing machine for generating arbitrar...
