AI and Counter synchronisation

[DavidT]

 Hi all, 

I have a question regarding sample synchronisation. I have a simple VI reading an analog input channel and two signals from encoders using the counters on a USB-6210 board. The VI has been attached. 

My question is - how synchronised are the two signals with the current setup? Ideally, I would like to synchronise the the three signals to the same timestamp but I am not 100% that they are in the current setup. I have a suspecion that the counter signals are out of phase with the analog input signal.

Any info would be appreciated.

Thanks,
Dave

Does this help?

It looks like their examples merge errors right before each Start node. This makes the Starts occur at approximately the same time in case the initialization of each takes longer for one than another.

As usual, with a bit more searching I found this link for an example program. Initialisation is very similar to what I had in my program so at this time I will assume that the analog and counter signals are synchronised.
