If the value of the timebase is changed the alignment system automatically performs an alignment or
alerts that an alignment is due.
Setting :CAL:FREQ:REF:FINE sets :CAL:FREQ:REF:MODE USER
This is unaffected by Preset but is set to the factory setting on a "Restore System Defaults->Align".

:CALibration:FREQuency:REFerence:COARse
ESA hardware contained two DAC controls for the Timebase. In X-Series the command
:CALibration:FREQuency:REFerence:FINE is the method for adjusting the timebase. The :COARse
command is provided as an alias to :FINE.
Prior to A.02.00
:CALibration:FREQuency:REFerence:COARse <integer>
:CALibration:FREQuency:REFerence:COARse?
:CAL:FREQ:REF:COAR 8191
This is an alias for CAL:FREQ:REF:FINE any change to COARse is reflected in FINE and vice-versa. See
CAL:FREQ:REF:FINE for description of functionality.
