Scan mode, sampling and inner clock Crio

Hello all,

I am new with labview and have few simple questions I need to be sure with them. I am using Crio-9076 with input card NI9234 and output card NI9263.

I have simple program where I generate chirp signal 100 sample/second. The chirp signal is continued to output channel in output car. At same time I measuring acceleration with 3 sensors via NI 9234. All this are in timed loop which is synchronized to scan mode.

1. The scan period is 1 ms, does this mean that the sample rate in hardware (cRio 9076) is 1 KHz even the sample rate of 9234 is 51.2 KS/s/ch and the sample rate of 9263 is 100kS/s/Ch?
2. Network publishing period is 10 ms, does this mean that even the sample rate of cRio 9076 is 1 KHz, published data and the data (points) I really can handle are sampled in 100?
3. The loop is synchronized with scan mode, does this mean that the loop’s rate is also 1 KHz (the data I get is anyway 100 Hz sampled)?
4. When I use output and input card are channels synchronized to start sampling at same time?

Thanks in advance
