NI NI-9253

  • High-Speed Sampling: The NI-9253 offers high-speed analog-to-digital conversion (ADC), typically with a sampling rate of 50 kS/s (kiloSamples per second). This allows it to capture fast-changing current fluctuations with good resolution.
  • Internal Master Timebase: The NI-9253 utilizes an internal master timebase with a frequency of 12.8 MHz. This ensures consistent and accurate timing for current measurements across all channels.
  • Programmable Hardware Filtering: The NI-9253 allows you to configure hardware filters to eliminate unwanted noise from the current signals. This improves the accuracy and reliability of your measurements.
  • Diagnostic Features: The NI-9253 includes built-in diagnostics, such as open-circuit detection, power supply monitoring, and user-configurable thresholds. These features can help you identify potential issues with the module or the connected sensors.
