Trident Multi-Parameter
Acoustic Analyzer
for
National Instruments Data Acquisition Cards
Trident is a multi-channel acoustic analyzer designed to utilize National Instruments data acquisition cards.
Trident conducts simultaneous FFT, 1/3 octave band and ISO 532B Loudness analysis on up to 8 channels. Trident uses the National Instruments Sound and Vibration Toolset host based signal processing VI’s. Real time performance is depended on the number of channels to be analyzed, the measurement bandwidth and the speed of the host processor.
Trident is an executable application and does not require National Instruments LabView to operate.
