• This application acquires the time waveform and calculates the FFT of 1 to 4 dynamic pressure sensors in real-time.  It displays the time waveforms on one graph and frequency spectrum (FFT) on the other graph.  You can pause the acquisition, then export the most recent second of time data and corresponding frequency data to Microsoft Excel.

Features:

• Automatically detects and installs 40 types of PC-based Data Acquisition devices from National Instruments
• Capable of handling up to 4 channels in real-time
• Sampling rate options of 100, 1000, 10000, 25000, or 50000 Samples/sec
• Calculates up to a 25,000 line FFT on up to 4 channels in real-time
• Compatible with IEPE or ICP pressure sensors (anything rated with a mV/PSI output)
• Displays a time waveform and saves the most recent second of time data from each channel
• Calculates the pressure spectrum (FFT) in real-time with exponential averaging
• Diplays the frequency in 1Hz increments
• Clearly specifies proper connections to the microphone in the ReadME
• Automatically opens Microsoft Excel and exports a time/date stamp along a 1 second time waveform sample per channel and and FFT at 1Hz increments

More Specifications:

• File Download Size: 115MB Installation Size on PC: 170MB (approximate)
• Uses a hanning window and a 3 second time constant for the FFT calculation
• Requires Microsoft Excel 2000 or later
• Requires Microsoft Windows 2000 or later
• Requires Adobe Acrobat Reader Ver. 6.0 or later
• Requires at lesat 256MB RAM and 600MHz Pentium processor equivalent or higher
