Trident
Trident, Version 5 for National Instrument DAQmx compatible hardware, is released.
April 2006
Nelson Acoustics has released Version 5 of its Trident Multi-Channel, Multi-Parameter acoustic measurement software application. Designed to take advantage of National Instrument's latest data acquisition hardware and the NI-DAQmx driver, Trident provides a plug-and-play measurement solution for most product noise emission and acoustic measurement applications.
Trident mX conducts simultaneous real-time analysis for proportional octave band (1/1, 1/3, 1/6, 1/12 or 1/24), high resolution FFT and ISO 532B Loudness analysis on up to 20 input channels. In addition, Version 5 adds simultaneous stream to disk time waveform recording of any or all input channels and the option to save the data to calibrated audio WAV format files for use with the Nelson Acoustics Sound Quality Analyzer. This allows Trident mX users to make all measurements typically needed for product
Trident mX was developed using National Instruments LabView programming language. It is then compiled to an executable application, providing plug-and-play functionality using the free LabView Run Time License. Trident mX also uses the proportional octave band filters from the National Instruments Sound and Vibration Toolset. These filters are certificated for IEC and ANSI compliance by National Instruments, allowing our Trident mX based systems to meet the underlying signal processing requirements of most acoustic test standards (such as the ISO 374x or ANSI S12.5x standards).
The Nelson Acoustics Trident mX application provides the following features and functionality:
Free running, real-time, proportional octave band, FFT and ISO 532B analysis
Leq, time averaged FFT and overall ISO 532B analysis
Built in calibration module
Stream to Disk, save to WAV file with level calibration
Real time audio monitoring of any input channel via the system sound card
Data export into MS Excel Template Files using ActiveX calls.
Options to export large FFT data files to text file output
User configurable input channels, sampling rates, frequency ranges and other setup parameters
User definable MS Excel export templates
The Nelson Acoustics Trident mX application is recommended for the following National Instruments Digital Signal Analyzer devices:
USB 9233 (some functionality limitations with this low-cost device)
The Nelson Acoustics Trident mX software application is available in several configurations to meet your budget and measurement needs:
>Trident mX Version 5, Multi-Channel, Multi-Board, Full Functionality (up to 20 channels from multiple boards)
>Trident mX Version 5, Multi-Channel, Single Board, Full Functionality (great solution for USB or single board PCI systems)
>Trident mX, Multi-Channel, Single Board, w/o Time Waveform Recording (most economical solution)
