NI 6008 increasing resolution by restricting range?

Solved!
Go to solution

Hello,

 

I am wondering whether or not it is possible to increase the resolution of the NI 6008 by restricting the range in the labview software?  For example if I set it to -5 to 5 V instead of -10 to10 V will I then get 10/(2^12) increments as opposed to 20/(2^12) resolution?  

 

Thanks

Yes, but you have to use one of the ranges that the hardware supports.  You can find the full list in the specifications.

 

If using differential measurements you may use ±5V.  If single-ended, you only have the option of ±10V.

Min/Max on the DAQmx Creat Virtual Channel VI rounds up to the nearest appropriate range on the DAQ. 

 

RSE on the 600x is fixed at ±10V.  Whatever you plumb into those min/max terminals, as long as you're using RSE you get the ±10V range.


Switching to differential gives you many more ranges, which are listed in the specs.
