common timabase

[Mart]

Hello,
just checking that something is not possible (as it appears to me).
I have multiple accelerometers connected to a single VINT hub. There is no way all these accelerometers would share the same time base so their reported timestamps would be aligned to the same reference time, right?
(E.g. the VINT hub would set the zero time for all the connected accelerometers)

You are correct- there is no built-in way to synchronize multiple accelerometer Phidgets. The timestamp provided in the event data is accurate for the acceleration data point for that event.

The best you could do is keep track of incoming data and interpolate to a standard time frame as data comes in so it can be synchronized when saving to a file or outputting to the screen. Of course if you're measuring vibrational data then any averaging or interpolation will cause some aliasing.
