Menu Function Descriptions
This section describes all panel keys and any associated menus displayed when they are pressed.
3.3.1
AUTO TUNE Key (Auto Tuning)
Used to display the maximum peak using the current conditions as a target span. When started, this
function gradually narrows the frequency span from the full span to the target span. Note that the initial
span must be within the band, and that the maximum level signal must be held from the moment it has
been found in a peak search to use this operation. Auto tuning can be interrupted by pressing any key on
the panel. (Note there is no menu associated with this panel key.)
