NI PXIe‑6368 781058-01 X-Series 16Simult AI 2MS/s 16Bit PXIe Multifunction DAQ Module

PN：781058-01 The PXIe‑6368 is single-slot 3U PXI Express X-Series high-performance multifunction DAQ, built for fully synchronous multi-channel low-noise measurement, fast power/mechanical transient capture, automotive ECU hardware-in-the-loop simulation and parallel component parametric testingNI. It integrates 16 independent fully differential analog input channels with dedicated 16-bit monotonic ADCs, guaranteed no missing codes, eliminating inter-channel phase skew and suppressing industrial common-mode interference for strain, thermocouple and piezoelectric sensor measurementNI.

Core analog input specs: 2 MS/s individual max sampling rate, 3.4 MHz -3dB analog bandwidth, four software-selectable DC ranges (±1/±2/±5/±10 V DC-coupled), low THD (-80 dBFS) for high-fidelity waveform reproduction, 75 dB CMRR @60Hz to filter power-line noise. Equipped with third-gen NI‑STC3 separate analog/digital timing core, 10 ns timing resolution and 50 ppm timebase accuracy, supporting retriggerable segmented burst measurement tasks without host reset interventionNI.

Analog output: 4 independent 16-bit DAC channels, max 3.3 MS/s synchronous update rate, ±10 V full scale, ±5 mA output drive, shared 8191-sample AO FIFO buffer. Digital I/O: 48 bidirectional TTL lines, 32 channels support 10 MHz hardware-timed pattern generation. Four independent 100 MHz 32-bit counters handle quadrature encoder decoding, PWM generation, frequency and event counting. Onboard 8182-sample dedicated AI FIFO enables DMA lossless long-duration continuous streaming.

Front dual 68-pin VHDCI high-density connectors split I/O into two independent groups, compatible with SHC68-68-EPM shielded multi-pair cables and SCB-68 terminal blocks. Native PXI star trigger and PXI_CLK10 shared clock realize multi-card coherent synchronous sampling to expand measurement channels for large vibration and NVH test benches. Controlled by unified NI‑DAQmx driver, compatible with Windows and LabVIEW Real-Time OS, widely deployed for structural vibration monitoring, power supply spike/ripple testing, vehicle ECU sensor HIL simulation, lithium battery screening and semiconductor multi-DUT parallel IV testingNI.

16 dedicated fully simultaneous differential ADCs deliver zero phase offset across all measurement points, a mandatory feature for modal vibration, acoustic array and multi-axis transient testing unavailable on multiplexed multifunction DAQ cards. 2 MS/s high single-channel sampling + 3.4 MHz wide bandwidth accurately captures narrow power spikes, motor voltage transients and ultrasound echo signals without attenuation or distortion. Third-gen NI‑STC3 dual independent timing engines support retriggerable segmented waveform acquisition, drastically boosting test throughput for unattended automated production screening. Four high-speed synchronous analog output channels generate synchronized arbitrary sensor waveforms for ECU hardware-in-the-loop simulation and power amplifier closed-loop linearity testing. Four independent 100 MHz 32-bit counters simultaneously execute multi-axis encoder position tracking and multi-channel PWM motor drive control without external counter hardware. Dual separated VHDCI front connectors isolate two groups of DUT wiring to reduce crosstalk and simplify modular mass-production ATE fixture layout. Dual onboard large-capacity FIFO buffers support hours of uninterrupted lossless waveform streaming for long-term vibration fatigue durability tests, greatly lowering host CPU data transfer overhead. Native PXI backplane trigger & clock bus synchronizes AI/AO/DIO/counter functions across multiple DAQ, SMU and switching matrix modules to build fully closed-loop multi-physics automated test platforms. Standardized NI‑DAQmx programming library provides pre-built vibration, transient and temperature measurement function blocks, significantly shortening LabVIEW HIL and production ATE development cycle compared to low-performance multiplexed DAQ devices. Compact single-slot modular design reserves abundant chassis expansion slots for additional measurement instruments.

Supports Windows 7/10/11 32/64-bit and LabVIEW Real-Time OS; fully compatible with LabVIEW, LabWindows/CVI, TestStand, NI‑DAQmx driver, NI MAX, supports C/C++/.NET/Python/MATLAB secondary development.
