Our measurement setup is using usb-1208FS to read mv/V sensor outputs into Dasylab.
Provided with 15V DC excitation and 2mv/V max output from sensor --> Max output into DAQ will be 30mV.
Analogue input module only allows a minimum of -1V to +1V of input range, this means a "theoretical" resolution of 2V/(2^12) = 0.49mV, which is pretty bad....
Hence my questions are:
1. Is this -1V to +1V input range specified by Dasylab or the usb-1208FS card?
2. Any suggestions/comments how can we improve this?
I would imagine either get a DAQ card with better resolution, maybe 16 bits instead of 12.
Would like to hear any comments and appreciate any inputs.
Regards
Kent
