有四款NI的高速数字化仪支持视频信号触发,它们分别是NI-5114/5122/5124/5142.这四款设备都支持标准定义视频信号(SDTV),但是只有NI-5114支持EDTV和HDTV。关于支持的信号格式与NI高速数字化仪的对应关系,请参照下表:
如果要在LabVIEW中使用高速数字化仪的视频触发功能,需要使用NIScope Configure Trigger (polymorphic) VI,并且为一下几个输入参数创建输入控件或者常量:
· Trigger Source
· Enable DC Restore
· Signal Format
· Polarity
· Trigger Coupling
· TV Event
