What's New?

SpectraDAQ-200: Our custom designed precision data acquisition sound card. Fixed gain steps for easy calibration, standard BNC connectors, exceptional dynamic range and extremely low distortion.

SpectraPLUS-RT: The baby brother to SpectraPLUS-SC - designed for users needing a high quality spectrum analyzer at a lower cost and a minimal learning curve.  Provides real time spectral analysis with Narrowband, 1/1 or 1/3 Octave resolution. 

SpectraPLUS-DT: Our multichannel analyzer supporting the Data Translation line of industrial data acquisition modules.  Up to 16 channels of acquisition and analysis with calibrated input levels, IEPE power, AC or DC coupling, and sampling rates as high as 2 MHz! 

Added support for recording and processing the tachometer input channel on the DT-9837 and DT-9826 modules.  Plot RPM versus Time as well as a dedicated RPM utility window.

Also added feature to Save and Load groups of files with one button click.

Expanded set of COM API functions.

Support for Installation in \Program Files and \My Documents

Added Sound Power level measurement utility (ISO-3744/3746).

Dynamic DC Offset - advanced algorithm for DC offset removal based on signal content.

Phase setting for the signal generator multi-tone signal type.

High resolution peak frequency readings when a Gaussian smoothing window type is used.  This provides very high frequency resolution in the Peak Frequency Utility window and also in the Data Logging and Automation peak frequency values

Added Run Control options to allow control of the update interval when using the Post Processing mode.  This allows you to "slow down" the analyzer for easier analysis when needed.

Added custom color option for the 3-D Surface plot.
Added special key press (-) to step backwards in the file.
Added option to automatically start all other open instances of the analyzer.
Added option to specify the number or tachometer ticks per revolution.

Added "Save All Files Using Prefix" option to easily manage large numbers of files.

Order Analysis:
Compute and display Order vs RPM on Spectrogram plot.
Display RPM values instead of Time on Spectrogram and 3-D Surface plots. 
Right click menu on Spectrogram to display Order plot.

Added Frequency Zoom toolbar controls to Spectrogram and 3-D Surface Plots

Added support for model DT9857 hardware

Added Cumulative Sound Exposure Level (C-SEL) measurement - right click on the time series plot. This is used for underwater acoustics applications.

Added the ability to export the peak wave form levels to a text file - intended for impulse type events such as pile driving.

Time Stamp information added to wave file.  Allows plots to display the actual clock time at which the data was recorded.  This new setting is on the <File> <File I/O Options> dialog box.

SpectraPLUS-SC Version 5.2: 

Name changed to SpectraPLUS-SC to differentiate from SpectraPLUS-DT

New COM API - object based automation engine!

Tabbed dialog box for all major setting (FFT settings, Scaling, Calibration, Triggering, Device I/O)

New "Run Control" parameters - Stop after N FFT's or elapsed time. Start delay option.

Tabbed dialog box for all major Plot Options

Log Magnitude Spectrum Scaling option

Plot Center control for time series plot

Data Logging improved and expanded - multiple items can be logged, separate file for each channel

New Trigger mode - run continuously after first trigger. Start signal generator on trigger event.

ASIO device driver support - better performance on certain hardware

File I/O parameter - automatically reopen wave file on program launch

Support for Installation in \Program Files and \My Documents

Added <Pull Cursor to Trace> and <Select All> to right click popup menus

New Splash Screen logo and plot watermark graphics

High resolution peak frequency readings when a Gaussian smoothing window type is used.  This provides very high frequency resolution in the Peak Frequency Utility window and also in the Data Logging and Automation peak frequency values

Added Run Control options to allow control of the update interval when using the Post Processing mode.  This allows you to "slow down" the analyzer for easier analysis when needed.

Added custom color option for the 3-D Surface plot.
Added special key press (-) to step backwards in the file.
Added option to automatically start all other open instances of the analyzer.

Added ability to quickly calibrate the analyzer to 0 dBr by right clicking on the spectrum plot.  This is useful for normalizing frequency response plots.

Added Frequency Zoom toolbar controls to Spectrogram and 3-D Surface Plots

Added support for the Digiducer USB accelerometer and reading the embedded calibration data from the device.

Added support for the SpectraDAQ-200 precision sound card calibration, input gain and IEPE features.

Added Cumulative Sound Exposure Level (C-SEL) measurement - right click on the time series plot. This is used for underwater acoustics applications.
