The StellarNet Init, Read, Close.vi is a general-purpose subVI for programming episodic spectral readings in LabVIEW. When called, it:
1) Initializes the instrument using either programmatic parameters or parameters stored on disk by SpectraWiz,
2) Acquires the spectrum, returning it to the calling VI as a graph-ready cluster that includes amplitude and wavelength information, and
3) Checks for error information from the .dll during the scan process, providing this in a LabVIEW-compatible format.

Since it is entirely self-contained, it can be used interactively as well as called as a subVI

The VI’s construction is straightforward. Initialization is performed and the values retrieved from sw.ini (the parameter file created by SpectraWiz) are retrieved. These are either used or supplanted by the front-panel (or wired-in) parameter values. A parameter update is performed, and the spectrum is retrieved. If an error occurs during the scan process, the LabVIEW error cluster is updated, allowing downstream processes to detect and handle the error gracefully.

The StellarNet SpectraWiz for LabVIEW spectrometry application is a full spectroscopy program that provides an easy-to-use graphical user interface for any of up to eight StellarNet USB spectrometers plus logging of process data on local or network storage.

It is designed to work independently of the SpectraWiz software utility. Spectrometer calibration parameters are managed by this application, either automatically in the case of BLUE-Wave and other advanced units or manually when the spectrometers are first connected.

The software utilizes an easy-to-use and space-efficient tabbed-panel design. Data logging and snapshots are supported, and time series may be logged to show changes of three wavelengths of any channel.

The software was entirely coded in LabVIEW 8.2 and interacts with the spectrometers via swdll.dll. In the graphical user interface, spectrometers (channels) are numbered 1-8, consistent with SpectraWiz usage.

The Graphical Display tab pane allows you to select three wavelengths for a given channel to monitor. You may hide or display each channel; the wavelength and the intensity at each cursor-selected wavelength is displayed in the legend. This information is also used in the Time Series tab pane.

After selecting the wavelengths to monitor on the Graphical Display tab pane, you may switch to the Time Series tab pane to view a rolling graph showing the behavior of the selected channel at those wavelengths over a period of time. For convenience, a real-time view of the full spectrometer data is presented in an inset graph at the upper left. You may clear the history of the rolling graph at any time by clicking the Clear History button at the upper left.

LabVIEW Mega Program in LabVIEW ver 7.x & 8.x – controls up to 8 simultaneous spectrometers & radiometers – includes source diagram and is compatible with Wizard-Runtime engine for chemometrics models

While SpectraWiz can run on virtually any computer, SpectraWiz LabVIEW does have some requirements.

If you are compiling code, you will need to compile in the 32-bit distribution of LabVIEW. Our driver is mixed-mode and can run in both 32-bit and 64-bit environments. However, the 64-bit LabVIEW program cannot compile mixed-mode while the 32-bit version can. Please make sure to install the 32-bit LabVIEW distribution on your 64-bit machine 

If you have any questions about if your version of LabVIEW will work with SpectraWiz LabVIEW feel free to reach out to your Application Scientist or email us at ContactUs@StellarNet.us
