NI DSA hardware devices provide the 24-bit measurement systems customers need to do testing of audio circuit designs, measure microphone signals and perform vibration measurements.
The NI Dynamic Signal Analyzer (DSA) and NI Dynamic Signal Generator (DSG) are designed to let you quickly use NI DSA hardware. The DSG executable provides a graphical interface for configuring test signals, configuring NI-DAQmx analog output hardware, and generating these signals with smooth rampup, rampdown, and update behavior. The DSA executable provides a graphical interface for configuring NI-DAQmx analog input hardware and performing interactive, cursor-based inspection of time and spectral data.
Included in this page is a link to the latest download of the DSA Soft Front Panels, overviews of how the panels work, and getting started videos of the panels being used for common tasks.
The NI DSG soft front panel provides the functionality of generating a variety of band-limited signal types with DAQmx devices that support analog output. You can use 24-bit analog output channels available on the PXIe 4463, NI 9260, PXI-4461, PCI-4461, and USB-4431. You may also use analog output channels on DAQmx MIO devices.
The NI DSA soft front panel provides a view of both the time domain and spectral domain of the acquired data. Windowing, overlap, averaging parameters can be accessed in Settings. Additional settings are available for data directory, user annotations, and recording duration. Configure acquisition in terms of time and frequency parameters. The SFP includes cursor functionality for interactive inspection of waveforms and spectra. Each graph has a cursor table that can be used to show key waveform and spectral parameters, or the cursor table can be hidden to maximize graph area.
Visibility, size, and color features are also implemented for presentations, screenshots, and printing.
The DSA soft front panel can be configured to update on a software analog reference trigger. The DSG soft front panel can be configured to start on a hardware digital start trigger. These triggers provide two different techniques to synchronize a set of DSA and DSG soft front panels.
The DSA and DSG soft front panels allow for quick interaction with NI DSA hardware for the purposes of understanding the performance and behavior of the hardware. These free soft front panels require LabVIEW and DAQmx Run-Time Engines but do not require installation of or provide a replacement for the measurement analysis available in the Sound and Vibration Toolkit. The source code versions of these soft front panels are available as LabVIEW Sample Projects installed with Sound and Vibration Toolkit (Base).
