The NI PCI-6115 is a 12-bit multifunction DAQ card delivering simultaneous analog input sampling at 10 MS/s per channel across four independent input channels. Dedicated ADCs per channel maximize throughput and multichannel accuracy while deep onboard memory—up to 64 MS—enables reliable high-bandwidth signal capture independent of bus bandwidth constraints. The card integrates two 12-bit analog output channels, eight TTL/CMOS digital I/O lines, and two 24-bit counters, all synchronized through hardware timing and digital triggering for mixed-signal applications. Software-selectable input ranges from ±0.2 V to ±42 V with configurable AC/DC coupling and antialias filters (50 kHz or 500 kHz) suit automotive, radar, sonar, and ultrasound environments. Analog outputs operate up to 4 MS/s per channel (single) or 2.5 MS/s (dual) into ±10 V loads with 130 V/ms slew rate. Digital I/O sustains 10 MB/s transfers via onboard FIFO. The PCI interface supports full-length chassis slots and multidevice synchronization via RTSI or PXI trigger buses, with configurable PFI lines for timing signal routing. NI-DAQmx driver simplifies programming across LabVIEW, LabWindows/CVI, Measurement Studio, ANSI C, and Visual Basic environments. SCXI module compatibility is available with NI-DAQmx 7.4 or later in parallel-mode operation.
