  • Reduce Memory Consumption – Collect different sample rates across channels and save only the data you need
  • Save Time – Simple and easy set-up allows for configuring network DAQ devices within SigmaDAQ, no additional software needed
  • Reduce Downtime, Maximize Uptime – With auto-reconnect, no user interaction is required during a lapse in connectivity
  • Flexible – Integrate with NI DAQ modules and third-party RS-232 devices from one solution


SigmaDAQ provides complete control of your data by monitoring multiple channels from multiple devices and chassis simultaneously, all from one solution.  To remove bottlenecks in testing environments, this full-featured software can deliver real-time mobile alerts containing visual and text notifications. SigmaDAQ is also built with smart technology which actively searches, reconnects and continues collecting data in the event of a lapse in device connectivity. As a superior and flexible data monitoring solution, SigmaDAQ provides automated Excel report generation and the unique ability to access data from multiple locations simultaneously.

Supported Hardware

  • Configure data acquisition of devices in one application. No need to configure hardware in NI Measurement and Automation Explorer (MAX).
  • Select independent sample rates for channels on the same device using auto-decimation.  Save only the data you need without cluttering your repository!
  • Auto detection and reconnection of disconnected devices and SMS text messaging. If your network goes down over the weekend SigmaDAQ will automatically reconnect and continue acquisition when the network is back up!
  • Burst and Continuous Sampling Modes that allow for continuous sampling or burst sampling on a specified interval (e.g. acquire data only every hour). Or a mix of both can be used!
  • View past or real-time data from multiple locations using SigmaDAQ Viewer.
  • Automatic creation of Excel reports. Data displayed on the graphs are converted to Excel charts automatically.
  • SMS text alerts with conditional monitoring can be configured on any channel – get a text message with an image of the data when the condition occurs.

System Requirements

  • Windows Vista or Windows 7/8
  • Microsoft Excel 2007 or higher for automated report generation
