The NI PXI-6115 S Series is a 12-bit multifunction DAQ module for PXI systems delivering simultaneous analog acquisition across four channels at 10 MS/s per channel. Dedicated ADCs per input channel ensure accurate transient and frequency measurements with minimal crosstalk. The module supports eight input ranges from ±0.2 V to ±42 V and includes software-configurable antialiasing filters at 50 kHz and 500 kHz (3-pole Bessel), with bypass capability. AC/DC coupling is selectable per channel. Beyond analog input, the PXI-6115 integrates two analog output channels (4 MS/s single-channel, 2.5 MS/s dual-channel), 8 digital I/O channels, and two 24-bit counters/timers. Onboard memory options of 32 MS or 64 MS enable extended capture of high-bandwidth signals. Analog and digital triggering, combined with RTSI and PXI trigger bus synchronization, support multi-device configurations. The module operates in hybrid-slot-compatible PXI systems and standard PXI slots.
