    Description
    Recommended use cases
    FlexLogger Professional (785748-3501)
    FlexLogger Professional, Subscription License, Download

    Recommended for automated, extensible data logging with NI data acquisition (DAQ) hardware. Automate tests using alarms, triggers, and events, and expand capabilities with plug-ins.

    Key Features

    • Multichassis synchronization—Synchronize multiple NI chassis for accurate, time-aligned measurements across high channel counts.
    • Logging triggers—Start, stop, or segment data recording automatically based on sensor thresholds or other conditions to capture only what matters.
    • Events—Respond to specific occurrences during a test, such as activating equipment when a condition is met (for example, start cooling fans when temperature exceeds a limit).
    • Automation APIs—Control and monitor FlexLogger from external applications (Python, NI LabVIEW, or NI TestStand), enabling integration into larger automated test systems.
    • Calculation channels—Perform real-time math on acquired data (averages, RMS, custom formulas) to track derived measurements as the test runs.
    • Plug-ins—Extend FlexLogger with custom LabVIEW or Python plug-ins to integrate third-party hardware, perform custom analysis, or connect to lab systems.
    • CAN/LIN logging—Acquire and log automotive network data alongside sensor measurements for complete vehicle or subsystem testing.
    LabVIEW+ Suite (788509-35)
    NI LabVIEW+ Suite, Subscription License, Download

    Recommended for engineers building full test and validation systems where modular code development and higher-level frameworks are needed to accelerate development for shorter time to market.

    The LabVIEW+ Suite includes the following products:

    • NI LabVIEW—Provides a graphical programming environment for test system development, enabling connectivity to any instrument and fully integrated user interfaces.
    • NI TestStand—Eliminates the need for time-intensive in-house sequencer development and maintenance by providing an off-the-shelf test management software for validation and production test.
    • NI DIAdem—Saves engineers hundreds of hours of manual data analysis and report creation with automation.
    • NI FlexLogger™ software—Simplifies data acquisition and data logging with interactive measurement setup for NI DAQ hardware.
    • NI InstrumentStudio™ software—Provides a central location for configuration, measurement, and automation.
