The NI AT-MIO-16X is a 16-bit multifunction DAQ board engineered for PC AT and EISA systems, delivering high-performance analog and digital I/O for measurement, control, and test applications. It provides 16 single-ended or 8 differential analog input channels at 100 ksamples/sec with ±10 V or 0 to +10 V ranges, plus two 16-bit analog output channels. The board integrates advanced timing, triggering, and synchronization capabilities via the RTSI bus for coordinated operation with other National Instruments AT Series boards.
