Minimum and Maximum ResBW

ResBW depends on the window type and the time length (main time length, gate time length, or Time trace length for digital demods).

For non-digital demods, the minimum ResBW depends on the maximum time length. For digital demods, ResBW cannot be set directly but is determined by the length of the Time trace.

The maximum ResBW is limited to 0.3 * Span.
