The NI PCI-6023E is a multifunction data acquisition board for PCI bus systems, delivering 16 analog input channels at 12-bit resolution with a maximum sampling rate of 200 kS/s. The card integrates 32 digital I/O lines and two 24-bit counter/timers, making it suitable for data logging, automated testing, process monitoring, laboratory automation, and manufacturing test environments. Its DAQ-STC ASIC timing controller manages seven 24-bit and three 16-bit counters with 50 ns timing resolution, supporting non-quadrature counting and PWM output modes. The analog front end accepts multiple input configurations—Non-Referenced Single-Ended (NRSE), Referenced Single-Ended (RSE), and Differential (DIFF)—on a per-channel basis across input ranges of ±10V, ±5V, ±0.5V, and ±0.05V. Input impedance is 100 GΩ in parallel with 100 pF. Measurement accuracy reaches ±1.0 LSB with full-scale step settling in 5 µs, backed by onboard software-controlled self-calibration. Temperature drift is minimized to less than 0.0010% of reading/°C.
