一种信号采集与回放系统
摘要：
本发明公开了一种信号采集与回放系统，包括AD数据采集模块与数据处理模块和数据交换模块连接，数据交换模块还与DA数据回放模块和存储模块连接，存储模块与数据交换系统连接，其中AD数据采集模块内设置有FMC子卡1、FMC子卡2和一个FPGA、DSP采集处理载板，通过FMC子卡1和FMC子卡2分别采集不同的信号数据，通过FPGA、DSP采集处理载板处理后发送至数据交换模块和数据处理模块。AD数据采集模块总共由3部分组成：两张不同采样率的FMC采集子卡和一块有FPGA和DSP组成的信号处理载板，采用两种不同的采样率的FMC采集子卡能够适应不同的情况，可以在不同的中心频率和带宽下进行信号的采集。
摘要（英）：

The invention discloses a signal collection and playback system. The system comprises an AD data collection module connected with a data processing module and a data exchange module, wherein the data exchange module is also connected with a DA data playback module and a storage module, and the storage module is connected with a data exchange system. An FMC daughter card 1, an FMC daughter card 2 and an FPGA and DSP collection processing carrier plate are arranged in the AD data collection module, wherein different signal data is collected through the FMC daughter card 1 and the FMC daughter card 2 respectively, and the signal data is sent to the data exchange module and the data processing module after being processed through the FPGA and DSP collection processing carrier plate. The AD data collection module is totally composed of three parts, namely the two FMC collection daughter cards with different sampling rates and the signal processing carrier plate composed of an FPGA and a DSP. By the adoption of the two FMC collection daughter cards with different sampling rates, the system can adapt to different conditions, and signal collection can be performed under different center frequencies and bandwidths.
