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-6343:
The PXIe-6343 is a particularly versatile model in the X series that impresses with its balanced combination of a high number of channels and a wide range of functions. It offers 32 analog inputs with 16-bit resolution and a sampling rate of up to 500 kS/s as well as 4 analog outputs with an update rate of 900 kS/s. There are also 48 digital I/O lines, which means that the PXIe-6343 offers significantly more flexibility for mixed signal applications than many other models in the series. This makes it ideal for test benches where the focus is equally on analog and digital signals, for example in electronics validation, hardware-in-the-loop tests or for multifunctional measurement systems.
Most important 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).
