Igor Pro is an interactive software environment for experimentation with scientific and engineering data and for the production of publication-quality graphs and page layouts. Igor has been used by tens of thousands of technical professionals since its introduction in 1989.

Download the fully-functional Igor Pro 9 and try it free for 30 days after installation. After 30 days, the Igor will lapse into limited functionality demo mode. The limitations of the demo mode are:

• Saving is disabled.
• The clipboard contents cannot be transferred to other programs.
• The printing output is lightly over-printed with Igor-related words.

To avoid these limitations, purchase an Igor Pro license to restore the full functionality.
