PXI-6551 temperature and time dependence of channel skew

Solved!
Go to solution

Hi All,

 

What is the temperature dependence of the room-temperature-calibrated channel skew for the HSDIO PXI-6551?  Suppose Dynamic Technology measures (after calibration or 'as left') the channel skew to be 60 ps for channel 3 at 23.2 degC.  How does this value change with temperature? 

 

There is also probably a known temporal drift.  How much will this vary over a two year period?

 

Please advise.  I'm looking into the possiblity of using the calibrated channel skew values to obtain higher accuracy.

 

Thanks!

 

Anand

Hi Anad,

 

I don't see any of this in our datasheets, I will need to look into this. Typically we have a range for how temperature affects a measurement, something like +/- X ppm/deg C.

It looks like Ryan M addressed this in another one of your posts:
