The NI X Series combines precise ±10 V analog inputs/outputs, flexible digital I/O and powerful counters/timers in a modular board family for PXI Express and PCI Express. Thanks to NI-DAQmx, you can use the same proven API and software tools (e.g. LabVIEW, FlexLogger, Python, C/C++) across all devices - for fast commissioning, stable measurements and easy scaling.
Available NI X-Series PXI & PCI models: PXIe-6357, PXIe-6353, PXIe-6351, PXIe-6343, PXIe-6323, PXIe-6321 and PCIe-6340, PCIe-6342, PCIe-6350, PCIe-6352, PCIe-6351.
Applications:
- Capture voltage signals (±10 V) with high resolution and speed, e.g. for validation, research and production tests.
- Conduct sensor and electronics tests: Stimulus/response measurements, modal/impact analysis, power and supply characterization.
- Use digital tasks such as event/pulse counting, PWM generation, quadrature encoder acquisition, trigger and clock synchronization.
- Generate and control signals: output analog waveforms, simulate sensors/signals or control external relays/LEDs.
Model variant PXIe-6333:
The PXIe-6323 is a model of the X series that is particularly designed for cost-efficient multifunction applications. It offers 32 analog inputs with 16-bit resolution and a sampling rate of up to 250 kS/s. In addition, 4 analog outputs with up to 900 kS/s and 48 digital I/O lines are available. This makes the PXIe-6323 a well-balanced solution for applications that require many channels but do not require extremely high sampling rates. Typical applications include medium-speed validation test benches, laboratory measurements or cost-sensitive projects where a wide range of functions is required.
Main technical data (depending on model):
- Analog inputs (A/I): 8-104 channels (DI/SE), 16-bit resolution, measuring range ±10 V.
- Max. Sampling rate (A/I): up to 1.25 MS/s per card with PXIe-6351/6353/6357; up to 1.25 MS/s (PCIe-6351); 500 kS/s (634x); 250 kS/s (632x).
- Analog outputs (A/O): 0/2/4 channels depending on model, 16-bit; update rates up to 2.86 MS/s (e.g. 6351) or up to 900 kS/s for 632x/634x.
- Digital I/O: 24 or 48 TTL/CMOS lines.
- Counter/timer: 4 × 32-bit with 100 MHz time base; functions include PWM, quadrature encoder, trigger, clock forwarding.
- Software ecosystem: NI-DAQmx; compatible with FlexLogger, LabVIEW/LabVIEW+ Suite and Python/C/C++.
- Bus/format: PXI Express (PXIe) or PCI Express (PCIe).
