MAESTRO-Pro provides an intuitive user experience with the MCA Emulator “Spectrum Window” being the focal point of operation. This approach simplifies routine processes, such as hardware control and count rate/peak evaluation, but also provides the base for more advanced operations such as calibration and spectrum evaluation with the most commonly used functions implemented as “hot keys” or toolbar buttons for rapid access.
The spectrum view offers all of the tools needed for basic MCA emulation including Hardware Control, Peak Navigation and Zoom functions, Region of Interest evaluation, Interactive Peak Search, Spectrum Overlay for comparison, Isotope Markers to identify nuclide common peaks, Summing/Subtraction of other spectra, and Spectrum Channel Smoothing. It also enables user preferences for color schemes and spectrum data views.
For easy access to spectra, the Multiple Detector Interface (MDI) mode can display up to 16 interactive windows (8 Live Detectors and 8 from Spectrum Files) with independent operation. Additionally, multiple detectors can be enabled for efficient group operations by synchronizing routine Start, Stop, and Clear processes from a single command.
Spectra are traditionally collected in Pulse Height Analysis (PHA) mode with data stored in channels related to pulse height. MAESTRO-Pro can also store data in “List Mode”, or time-correlated events, with the ability to filter the events after acquisition by user-defined time ranges. This process allows long acquisitions to be scanned by shorter time intervals to identify precisely when activity was detected or interrogate a specific period of interest.
Basic sample measurements are simple processes when using the standard “Ask on Start” options. Just check the user inputs required for each measurement and the user is prompted to select the applicable files or input sample data when the acquisition is started. Additional options may be set to automatically save and analyze the spectrum and print the analysis report.
Key User Interface Features:
- Spectrum View
- View up to 8 live detectors and 8 saved spectra simultaneously
- Real Time display update during acquisition.
- Zoom In/Out independent of Full Spectrum Window

MAESTRO-Pro is not intended for full spectrum analysis like GammaVision
, but it does include basic Region of Interest (ROI) functions and reporting options, interactive peak fitting, and the ability to display the detailed analysis results generated by GammaVision analysis engines for data evaluation.

- Fast Mariscotti Peak Search to instantly mark Regions of Interest
- Region of Interest (ROI) reports in Column or Paragraph format
- Isotope markers with peak amplitude estimation to confirm peak origin
- Interactive “Jump to Peak” by ROI, Library Energy, or Peak Search options
- Spectrum overlay for direct visual comparison to a reference
- Combine Spectra by Channel Summing or Stripping
- Spectrum Smoothing to improve statistically poor peak shape

- Variable Number of Background Channels
- Improved FWHM accuracy when peak centroid falls between channels
An accurate calibration is essential for proper peak identification and quantification – particularly for complex spectra with closely overlapping peaks. This can be a tedious and time-consuming process with some systems, but it’s a breeze with the MAESTRO-Pro Calibration Wizard. Simply acquire a spectrum, load a calibration library and source certificate, and the calibration is complete! The calibration process can also be automated as part of the routine counting processes.
Calibrations created within MAESTRO-Pro are not only used for the basic analysis functions within this application, but are also fully compatible with GammaVision and other ORTEC applications.
Key Calibration Features:

- Calibration Processes
- Automatic Energy Calibration (U.S. Patent No. 6,006,162)
- Calibration Wizard
- Semi-Automatic and Manual/Interactive
- Automation using Job Functions
- Automatic Energy Calibration Adjustment during Analysis

Although the toolbar and menus options are simple and intuitive, this method of operation does not guarantee consistent processing that is often needed for measurements performed frequently or by different individuals. In these circumstances a more structured approach using simple text scripts called “Jobs” may be preferred. This feature enables every detail of the process to be defined in advance or created dynamically by a custom user interface. Virtually all of the hardware commands, analysis parameters, and processes required measurements can be programmed for consistent and reliable results every time.
Key Automation Features:
- Simple Text Scripts require no prior programming experience
- Define and Set any Analysis Parameter or prompt for user input
- All Hardware Control functions available
- Jobs may be dynamically generated by custom data entry interfaces
- Custom Variables available for advanced programming
- Run External Applications to set parameters and automate data integration
The interface between hardware and software is provided through the ORTEC CONNECTIONS framework which supports up to 250 detectors across a local network. This application layer encompasses all of the hardware drivers and communication protocols that are necessary for software applications to control the MCB (Multi-Channel Buffer) instruments. Hardware controls are accessed through MCB Property pages that are integrated with MAESTRO-Pro and other standard ORTEC applications.
Windows 10 64-bit hardware compatibility is available for all ORTEC instruments that use USB and TCP/IP connectivity. Instruments that are dependent on a host computer, such as plug-cards or USB devices, can optionally be shared on a network through local MCB Servers allowing full control from remote locations.
