ScopeFIR's primary design window consists for four panes:

• Upper left - Specification Editor, for editing FIR filter specifications.
• Upper right - Coefficient Editor, for modifying coefficients produced automatically by ScopeFIR.
• Lower left - Frequency Response Plot, for examining the filter's response at various frequencies
• Lower Right - Impulse Response Plot, essentially a graph of the coefficients.

You can resize these windows by clicking/dragging the lines that divide them.  Also, if you want to see the coefficients or the plots in a larger, separate window, you can select commands in the View menu, or click on icons at the top.
