We have build a system that has a drive unit that is driving a wheel. We measure the speed of this wheel with a puls sensor on this wheel. This puls is connected to a SCXI-1126 module which is connected to a daq board in multiplexed mode.
Also on this wheel a frequency meter with a can interface is connected.
When we know read out very fast the analog board and the latest can messages, we see that there is a delay between the can values and the analog values from the SCXI 1126. In fact the SCXI results are 100ms later then the can results. Is there a delay on the SCXI-1126? Also the edges when changing the frequency into a sweep are not that charp with the SCXI-1126. (We use a 12V puls signa
l, 50%DC and 1 Hz filtering)
