Hardware

  • NI-9215

Driver

  • NI-DAQmx

Issue Details

The input voltage of the NI-9215 is ±10 V but I just need to acquire a signal which goes from 0 to 10 V: is it possible to modify the input range to 0-10 V in order to take advantage of all the 16 bit of resolution? 

Solution

0-10 V is not supported: acquiring a 0-10 V signal with a ±10 V module with 16 bit resolution means that you're losing just 1 bit of resolution (the one used for the sign).
