fifo size for digital output generation (e.g. PCI-6284)

[markjoe]

Hi all,

I have a question whether the mentioned card is suitable for my goals. I need to generate 20 different digital waveforms and they need repeating after the waveform is ended. The mentioned card can retransmit the fifo, so that sounds OK. I understand the fifo can hold 2047 values. Is this number per output? So, can I supply a waveform consisting of max. 2047 values per channel, thus in my case (want to output 20 channels) supply 20 different waveforms to the 20 channels? I guess the clock is shared?

Thanks, Mark

Hello Mark,

The knowledge base linked below will explain exactly how the fifo on an M-Series Board works:
