fpga analog sample rate

[Tom_denso]

What is the quickest rate which you can read/write an analog channel in fpga (with a 7831 R card)?
If you attempt to read/write quicker than is possible would it cause an error when running the fpga VI from real time?

To read, about 4.3 microseconds. You can't sample any faster because the
function won't return any faster. If you try to read the same value in two
different loops in your vi, each will sample every 8.6 us. To avoid this
performance hit, I've fed the same signal to two inputs.

You can write about every 1 us. If you want to read, process, and then
write a signal, you can use interpolation to output 4 values for every one
input to achieve the best possible fineness. To obtain the best
performance, it is necessary to carefully arrange the read, process, and
write functions so that waiting is minimized.
