The NI PXI-6040E is a 12-bit multifunction data acquisition module designed for integration into PXI systems. It delivers 16 single-ended (or 8 differential) analog input channels at 500 kS/s aggregate sampling, plus 8 digital I/O lines, 2 counter/timers, and RTSI synchronization for seamless multi-module coordination. Software-selectable input ranges (±10 V, ±5 V, ±1 V, ±0.5 V) and user-calibratable offset/gain errors accommodate diverse signal conditioning requirements. The module operates from the PXI backplane with typical power consumption of 3.0 W, making it ideal for embedded test systems requiring synchronized analog, digital, and timing functions.
