Recall
Recall sets up the front panel by recalling a front-panel setup from a selected
setup memory. The message "Setup recalled" is displayed at the top-left
corner of the screen indicating the setup was recalled.
If a setup is recalled and you changed plug-ins, the oscilloscope matches the
recalled channel settings as close as possible to capabilities of the new
plug-in.
Default Setup
The default setup key returns the oscilloscope to its default settings. The
default settings place the oscilloscope in a known operating condition. This
known operating condition is used as a starting point in the service
procedures. You may find it helpful to use this known operating condition as
a starting point when setting up the oscilloscope to view signals.
