    Chapter 4 Analog Input If data cannot be transferred across the bus fast enough, the FIFO becomes full. New acquisitions overwrite data in the FIFO before it can be transferred to host memory. The device generates an error in this case. With continuous operations, if the user program does not read data out of the PC buffer fast enough to keep up with the data transfer, the buffer could reach an overflow condition, causing an error to be generated.

  • Page 269 Appendix C Troubleshooting How can I use the AI Sample Clock and AI Convert Clock signals on an M Series device to sample the AI channel(s)? M Series devices use AI Sample Clock (ai/SampleClock) and AI Convert Clock (ai/ConvertClock) to perform interval sampling. As Figure C-1 shows, AI Sample Clock controls the sample period, which is determined by the following equation: 1/sample period = sample rate Figure C-1.
