Virtual Spectrum Analyzer
The ATTI Virtual Spectrum Analyzer (VSA) is a supplementary software program that interfaces directly with the ATTI Programmable Video Generator and Analyzer (PVGA). In normal operation, the PVGA functions as a highly flexible video frame grabber with operational modes that support a broad range of video formats. The VSA serves as an extension to the capabilities of the video frame grabber by adding a graphical interface, continuous near real time image reconstruction, image enhancement, and visual redisplay on the host computer's monitor. By utilizing assets already present on the testing platform, the physical requirement for an external display unit to monitor signals generated by the instrumentation under test is eliminated. The PVGA-VSA combine to form a complete solution set for the generation and acquisition of video signals within the confines of a single C-sized VXI slot.
This product is protected by one or more of the following patents: 6396536, 6502045, 7289159, 7180477, 7253792, 7289159, 7495674, 7768533, 7978218

The ATTI VSA expands upon the power of the ATTI PVGA by providing value-added features previously unavailable in the VXI form factor. The ATTI PVGA is a true VXI instrument integrating multiple function, multiple output video generation, and video-specific digitizer/analyzer capabilities into a complete general purpose test platform for military or commercial applications. The capacity of the PVGA to operate with nonstandard military video variants is unsurpassed, both in the generation and analysis modes of operation.
The PVGA acquisition unit is capable of capturing the following video modes:
Composite Video (1 wire (B/W) analog)
Composite Video (3 wire (RGB) analog)
Composite Video (digital- 32K colors: 3 channels, 5 bits per channel)
Raster Video (3 wire- scanned XYZ)
Stroke Video (3 wire- direct XYZ)
The software driver for the PVGA provides single-frame capture capability with numerous measurement modes. Once the PVGA has been programmed by the PVGA driver, the VSA is designed to take direct control of the PVGA and automatically interlace the frame capture sequence with simultaneous data uploads. Upon completion of each data upload, the image is manipulated by the VSA post-processor where it may be enhanced, magnified, or averaged. Finally, the processed image is presented to the operator in a scalable window on the host computer's monitor.
The benefits of the PVGA-VSA package include:
The elimination of bulky auxiliary display units used to present UUT video images
The elimination of all storage, transport, mounting, alignment, and wiring issues associated with auxiliary display units
All video test functionality occupies a single VXI slot
Unlike many commercial instruments, the flexibility of the PVGA-VSA frame acquisition unit allows capture and display operations over an extremely wide range of video standards and variants
The ATTI Virtual Spectrum Analyzer was designed to be a unique and effective software enhancement to the PVGA video test instrument. With no additional hardware requirements, the PVGA is transformed into a virtual imaging monitor capable of viewing a wide range of video standards and variants over a wide range of video formats.
