WIFI Synchronization

Chris Many thanks. This sounds encouraging to me.  Would it be different for continuous data acquisition? I mean if the time required to configure the hardware for continuous DAQ will increase the offset between the two systems? Do you think if it is worth trying to "Tee" a sinusoidal signal (say 100Hz) to the two systems and calculate the offset by checking the phase difference between signals from the two systems?  Thanks. Ian

Ian,

Configuring the hardware for continuous will not make a difference. All the configuration will be done before the task is started so this will not create anymore offset. I saw similar results when I set up a "Tee". The phase difference of the samples themselves were only separated by a few microseconds.

I did, however, see quite a difference in the t0's. This is caused by the execution of the VI's starting the task being software timed. You can control this somewhat in LabVIEW using a sequence structure, but it still could vary depending on the resources and usage of your computer. This could cause around 1ms or even more of a difference.
