About State and User Tags
When any of the State settings (listed above) are changed during a recording,
a ‘state tag’ is inserted at the first trace number to be recorded with the new
setting.
In addition, you can insert a ‘User Tag’ at any time during a recording session
to indicate an external event, such as when an antenna is moved. During
playback, you can move quickly to any of these tags, or scroll through these
tags.
A symbol is used on the screen annotation to distinguish a User Tag from a
State Tag when scrolling through tags during playback.
