Embodiment Construction
[0020] The principle of the AWG is to intercept a cycle of the signal waveform to be reproduced for uniform sampling and store it in the memory, and then read the data in the memory in order to obtain the required waveform through the digital-to-analog converter and filter network. An AWG will usually contain multiple DACs.
[0021] Ethernet is a computer local area network technology. The IEEE 802.3 standard established by the IEEE establishes the technical standard of Ethernet, which specifies the content of the physical layer connection, electronic signal and medium access layer protocol. Ethernet is currently the most widely used LAN technology.
[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0023] The invention provide...

The invention discloses an implementation method of a measurement and control board card based on a network interface, and relates to the technical field of measurement and control board cards. A measurement and control board is customized. The measurement and control board card comprises an FPGA module, a digital-to-analog conversion module, a clock module, an overheating protection module and anetwork module. The upper computer sends required waveform data and a control instruction to the FPGA module through the network module. The FPGA module issues required waveform data to the digital-to-analog conversion module. The digital-to-analog conversion module outputs required waveforms, the clock module provides a clock source to facilitate data synchronization among the digital-to-analog conversion modules in the measurement and control board card and among the digital-to-analog conversion modules of the plurality of measurement and control board cards, and the overheating protection module cuts off power supply of a whole board power supply when detecting that the FPGA module is overheated, so that the stability of the measurement and control board card is ensured.
Description
technical field [0001] The invention discloses an implementation method, relates to the technical field of measurement and control boards, in particular to a method for realizing a measurement and control board based on a network interface. Background technique [0002] AWG (Arbitrary Waveform Generator, Arbitrary Waveform Generator), a single AWG board is often difficult to meet the requirements, more and more applications need to be able to control multiple AWG boards at the same time, but there is no quick way to achieve multiple measurement and control boards Synchronous control, a measurement and control board that meets the needs of more channels of arbitrary waveform generation. Contents of the invention [0003] Aiming at the problems of the prior art, the present invention provides a method for realizing a measurement and control board based on a network interface, which has the characteristics of strong versatility, simple implementation, etc., and has broad appl...
