these triggering modes make it easy to synchronize can, and usb frames 这些触发模式能容易实现与can和usb帧的同步
new trigger mode 支座可调
forcetrigger : it can let hardware auto generate a proper trigger when you can't get trigger in auto trigger mode 使硬件自动产生一个适当的触发,当你在自动方式时不能得到触发。
according to the reserved scanning address sequence, channel range and trigger mode, it can sample data . the module can change sample time and sample length . the sample data can be disposed by the cpu on board and then be stored in 64k ram 本模块可根据预先设置的扫描地址序列、通道量程和触发方式进行数据采集,采样时钟和采样长度可以改变,测得数据经过板上cpu的实时处理后在64k的存储器中缓存。
it contains two a / d channels, every channel has a 4kx 16bit buffer . it has three flexible trigger modes : inner trig, outer trig and software trig . vvp platform can support up to 4 plug-in boards ( 8 channel a / d ) to work together 该模块作为一块vvp仪器平台上的插板,采用20msps的16位ad转换器,一块插板上设计了2个高速ad转换通道,每个通道有4k16位的缓冲存储器,可以内部触发、外部触发和软件触发。
