National Instruments Data Logging Software

PC-based data loggers provide enhanced functionality over traditional stand-alone data loggers because device functionality is defined by software running on the PC. National Instruments offers several levels of data logging to fit your application needs: NI InstantDAQ, LabVIEW SignalExpress, and LabVIEW. Each option provides a different balance of ease of use and flexibility.

NI InstantDAQ

National Instruments devices with NI InstantDAQ technology provide the quickest and easiest way to log data. Simply plug the device into a computer and built-in software for graphing and logging data is automatically loaded. No prior driver installation is required.

Devices with NI InstantDAQ also include downloadable ready-to-run applications that offer additional functionality such as generating alarms, conditional logging, scheduled logging, and logging to a spreadsheet file.

NI LabVIEW SignalExpress

LabVIEW SignalExpress expands the functionality of NI InstantDAQ software by providing an interactive environment for graphing and logging data without any programming required. LabVIEW SignalExpress LE is included free with all NI data acquisition (DAQ) devices and includes the following:

  • Data view for interactive graphing and logging
  • Channel view for simultaneously configuring multiple channels
  • Connection diagram for easy signal connection
  • One-click data export to Microsoft Excel

The full version of LabVIEW SignalExpress is available as an upgrade to LabVIEW SignalExpress LE and includes the following enhanced functionality:

  • Built-in time and frequency analysis functions for max and min values, averages, root-mean-square (RMS), masks, limits, fast Fourier transforms (FFT), octave analysis, tone extraction, lowpass filtering, and highpass filtering
  • Customizable user interface with graphs, charts, thermometers, meters, gauges, and LEDs
  • Alarming, dynamic events, and start and stop conditions for data logs
  • Project report generation

For data-logging applications requiring even further customization, LabVIEW provides the most flexible solution. Using LabVIEW, you drag and drop controls and graphs to create GUIs and wire together function blocks to define software functionality. LabVIEW includes the following:

  • Code generation wizards for configuring measurement tasks
  • High-speed streaming to disk at rights up to 1 GB/s
  • Customizable user interface with graphs, charts, thermometers, meters, gauges, and LEDs
  • Custom timing, triggering, event, and alarm conditions
  • Hundreds of math, signal processing, and analysis functions
  • Logging to custom file formats and databases
  • Application distribution as executables
