Analog Input
The analog input section of each PCI-MIO E Series board is software
configurable. You can select different analog input configurations
through application software designed to control the PCI-MIO E Series
boards. The following sections describe in detail each of the analog
input categories.
Input Mode
The PCI-MIO E Series boards have three different input modes—
nonreferenced single-ended (NRSE) input, referenced single-ended
(RSE) input, and differential (DIFF) input. The single-ended input
configurations provide up to 16 channels. The DIFF input configuration
provides up to eight channels. Input modes are programmed on a per
