数据采集

您好！

      我现在要对一个数字信号进行采集，Labview版本是8.2，硬件用PXI-6259.问题是这样的：该数字信号是一个占空比随机，高电平宽度和低电平宽度都是0.1ms的倍数，但是不超过1ms，即：该数字信号的频率是1K到10K。我想用6259进行采集，现在的问题是我利用外部时钟40Khz进行采集，并且利用digital waveform显示了采集到的波形，但是我想连续的显示出其电平数字：区别于digital waveform上的0和1显示。而是每0.1ms显示一个数字是1还是0.比如：高电平宽度是0.5ms时显示5个1，低电平宽度是0.2ms时显示2个0，如此，并且是连续采样，连续显示。能不能实现？谢谢各位高手。
