Cross-Hair and Interpolator Tool
The Cross-Hair is a passive tool that constantly reports the exact frequency at the cursor position.
The interpolator is an active tool. It always searches for the nearest maximum and reports its frequency. It shows the information in a tooltip, therefore after you stop moving the mouse.
- To measure the distance between two peaks with the interpolator, click the first peak and drag to the other one.
- Press Shift-J to stamp the message permanently (it becomes an editable note).
- To copy the frequency value, the interpolator tool is not required. Right-click and choose Copy Frequency.
- To measure a distance and annotate the spectrum with the value, first select a region with the normal pointer, then select the interpolator tool.
Use the interpolator for rapid examination of the spectrum. Use the J Manager for an in-depth analysis.
