PXI-6133+Measurement Hardware DDK: Binary data when input voltage exceeds the input range

[ralfn_2]

Hi there,

a colleague is using the NI Measurement Hardware DDK (Driver Development Kit) and a PXI-6133.

He reads out the binary data and is wondering about the converted value. With an selected input range of +-1.25 V and a slight higher input-voltage (1,6 ... 1,8 V) the converted value is over 12 V.

His questions are:

 - Which binary value do I get when the input voltage exeeds the Maximum or the Minimum of the input range?
 - Is there a limit when exeeded the binary value jumps to a "emergency-value" (like a clipping)

 
Thank you very much for your help.  


With best regards,
Ralf N.

Hi there, 

a Happy New Year!  

Any news?

Thanks,

Hi Ralf,

Happy New Year indeed 😄 Let's see if we can figure out what's going on.

The first questions I have are about your colleague's program:

1. Is he using one of the S Series examples from the DDK? If so, which one?
2. How does he convert from the ADC's raw codes to Volts?
3. When applying out-of-range voltages to the board, what binary values does he read?
