these triggering modes make it easy to synchronize can, and usb frames 這些觸發(fā)模式能容易實(shí)現(xiàn)與can和usb幀的同步
new trigger mode 支座可調(diào)
forcetrigger : it can let hardware auto generate a proper trigger when you can't get trigger in auto trigger mode 使硬件自動(dòng)產(chǎn)生一個(gè)適當(dāng)?shù)挠|發(fā),當(dāng)你在自動(dòng)方式時(shí)不能得到觸發(fā)。
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 本模塊可根據(jù)預(yù)先設(shè)置的掃描地址序列、通道量程和觸發(fā)方式進(jìn)行數(shù)據(jù)采集,采樣時(shí)鐘和采樣長(zhǎng)度可以改變,測(cè)得數(shù)據(jù)經(jīng)過板上cpu的實(shí)時(shí)處理后在64k的存儲(chǔ)器中緩存。
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 該模塊作為一塊vvp儀器平臺(tái)上的插板,采用20msps的16位ad轉(zhuǎn)換器,一塊插板上設(shè)計(jì)了2個(gè)高速ad轉(zhuǎn)換通道,每個(gè)通道有4k16位的緩沖存儲(chǔ)器,可以內(nèi)部觸發(fā)、外部觸發(fā)和軟件觸發(fā)。
