Converting NI 9320 Data (FPGA Interface)

Set the Calibration Mode to Calibrated in the C Series Module Properties dialog box for the NI 9320 if you want the FPGA I/O Node to return calibrated, fixed-point data from the module in units of volts.

Set the Calibration Mode to Raw if you want the FPGA I/O Node to return calibrated, binary data from the module. If you set the Calibration Mode to Raw, you must convert the binary values to engineering units in the host VI. Use the following equations to convert binary voltage values to volts in the host VI.

V o l t s   =   B i n a r y   V a l u e   ×   320 , 435   n V L S B

where Binary Value is the value returned by the FPGA I/O Node.
