Hello,
I was wonderinf whether this board supports TTL trigger-In. Idea is to sequentially increase voltage on the analog output with each TLL high comming in? Is that possible? Can I load sequence of states into this board?
Thank you

What you describe as a “trigger” is what we call a “clock”, or more specifically an external clock. The PCI-DDA series has only a memory depth of one sample per channel, and does not offer trigger or clocking capability. Therefore it will not meet your stated needs.
The D/A channels on many of our multi-function PCI DAQ devices, such as the PCI-DAS6014, offer both FIFO memory and external clock capability. The D/A channels on many of our multi-function DAQ devices (such as the USB-1208HS-2AO/4AO, and USB-1608GX-2AO) do so as well, plus they add external trigger capability. Our software drivers for these devices allow you to create an array of data points in advance, and specify that they will be paced out (i.e. one output per edge) by an external TTL signal.
