图2.1 软件界面功能区块 #### 5.1 参数配置区功能 
图2.2 配置功能设置区 1) 采样频率控件。 此控件设计成下拉菜单的形式，下拉菜单包括102.4m、409.6m、500m三个选项。409.6m和500m设置命令发送给1G AD采样卡。102.4m设置命令发送给时钟卡。 2) 触发方式控件。 此控件设计成下拉菜单的形式，下拉菜单包括内触发和外触发。当1中设置成409.6m或500m的选项时，命令下发给1G AD采样卡。当1中设置成102.4m的选项时，命令下发给时钟卡。 3) 时钟源控件，此控件设计成下拉菜单的形式，菜单包括内时钟和外时钟。此命令发送给时钟卡。 4) 配置控件，点击此控件对AD进行配置，当采样频率设置成409.6m或500m时，命令发送给1G AD采集板，当采样频率设置成102.4m时，命令发送给时钟卡。 #### 5. 2 发送功能介绍 
图2.3 发送功能设置区 1) 频率控件设计成填写方式，位宽占4个字节，单位10HZ。 2) 射频衰减控件设计成下拉方式，下拉菜单包括2'b00：不衰减、2'b01：衰减 10dB、2'b10：衰减20dB、2'b11：衰减30dB，射频衰减占用一个字节的低2位。 3) 模式识别控件设计成下拉菜单的形式，下拉菜单包括2'b00：常规模式、2'b01：低噪声模式，模式识别占用一个字节的2位。 4) 中频衰减控件设计成填写方式，单位1dB，占用一个字节的低六位。 5) 带宽选择控件设计成下拉菜单的方式，菜单包括2'b01：带宽3000kHz/500kHz、2'b10：带宽20mHz、2'b11：带宽40mHz。 6) 发送控件用于当以上控件都设置完成之后，点击此控件，上位机以PCIE DMA的方式下发给板卡，DMA大小位8字节。 #### 5 .3 采集操作区 
图2.3 采集操作区 1) 开始采集控件，当采样频率设置成409.6m或500m时，命令发送给1G AD采集板，当采样频率设置成102.4m时，命令发送给时钟卡。开始采集数据。 2) 停止采集控件，当采样频率设置成409.6m或500m时，命令发送给1G AD采集板，当采样频率设置成102.4m时，命令发送给时钟卡。停止采集数据。 3) 点击清除控件会清除板载内存的数据。 #### 5. 4 显示区 
图2.5 显示区 波形显示区。横坐标为播放文件的数据点序号，纵坐标为电压值。 #### 5 .5 回放操作区 
图2.5 回放操作区 1) 回放文件路径浏览按钮。浏览需要回放的文件，选择好文件后，文件路径会自动显示到按钮左侧的编辑框中。 2) 加载按钮。浏览路径完成后，点击加载按钮，程序加载待回放的文件到程序，等待播放。 3) 开始回放按钮。加载完文件后，点击开始回放按钮，开始回放。 4) 暂停回放按钮。根据实际情况，可以点击停止回放按钮，查看波形。 5) 快进按钮。根据实际需要，调节回放速度。 6) 振幅缩放按钮。根据实际需要，调节波形在显示区的振幅显示范围，便于波形查看。 7) "+"和"-"按钮。根据实际需要，调节波形在显示区的横轴显示范围，便于波形查看。 | |
