Copy (Edit)

The Copy command will write the contents of the currently selected item to the clipboard:

Trace hotspot selected - click Copy to write the unscaled version of the trace hotspot to the clipboard, along with the associated base units. For example, right-click on the Center Frequency hotspot on a Spectrum trace, then select Edit > Copy and the value "1000000000 Hz" is copied to the clipboard (assuming default setup).
Marker readout line selected in the Markers Window - click Copy to write the reverse-highlighted value to the clipboard.
Trace data - when no trace hotspots are selected, click Copy to write the trace data for the active trace to the clipboard. Then the data can be pasted into another Windows application, such as Microsoft Excel, for analysis, manipulation, or documentation.
