The Cross-Hair and Interpolator Tools
The Cross-Hair is a passive tool that continuously 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. The information is displayed in a tooltip once the cursor stops moving.
- To measure the distance between two peaks with the interpolator, click the first peak and drag to the other peak.
- Press Shift-J to convert the message into a permanent annotation.
- 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 pointer tool, then choose the interpolator tool.
Use the interpolator for rapid examination of the spectrum. Use the J Manager for an in-depth analysis.
