The Spectrum panel has a property Frequency Click that takes a receiver, spectrum or IQ trace. If that property is set, the receiver frequency and bandwidth are visible on the displayed spectrum (assuming that the receiver frequency is in the spectrum span). The receiver is now frequency-controlled by a click on the spectrum.

It’s possible to have multiple properties windows. You can see and change the settings of more than one instrument/decoder at the same time!

To open the properties windows, double-click on the instrument/decoder node in the explorer.
