National Instruments offers a variety of 32-channel analog input 32 channels into a single channel of the DAQ
modules for SCXI. The programmable gain and filter settings
device, and you can add modules to increase
are ideal for conditioning a variety of millivolt, volt, current, and channel count.

One year specifications. Includes error added by 16-bit E-series MIO immediately after an E-series internal calibration. Absolute accuracy is (reading) (% of reading) + (offset) + (system noise). If module
*
temperature is beyond the range 15 to 35 ˚C, include the added term [(reading) (gain drift) + offset drift] ∆T, where ∆T is the absolute temperature difference between the module and 15 or 35 ˚C, whichever

is smaller. Refer to page 436 for example calculations.
