Using SheetScan

SheetScan allows you to extract characteristics data from graphics such as data sheets which have been scanned and saved in any of the following formats: .bmp, .dib, .jpg, .gif, .tif, .tga, .pcx, .htm, or .html.

Access SheetScan from the Datasets window:

• For project-level datasets, click Project > Datasets.
• For design-level datasets, click HFSS > Design Datasets.

In addition to importing graphic files directly, SheetScan also can be used to browse the Internet for datasheet information and transfer a snapshot of the web page to the SheetScan editor where you can map axes on the image as an overlay. You can then manually add datapoints to approximate the characteristic curve(s) on the datasheet.The sampled data can then be converted to Ansys Electronics Desktop format, and the extracted data exported to an Ansys Electronics Desktop dataset or saved to a tab-delimited file.

The process for creating a dataset using SheetScan involves four basic operations:

• Loading a datasheet into SheetScan.
• Defining a coordinate system for the imported datasheet picture.
• Defining a characteristic curve using the datasheet picture as reference.
• Exporting the characteristic curve data to a file or to a dataset.
