Align Now, 20 Hz to 30 MHz
Immediately executes an alignment of the receiver subsystem. The receiver will stop any measurement
currently underway, perform the alignment, and then restart the measurement from the beginning
(similar to pressing the Restart key).
The query form of the remote commands (:CALibration:RFPSelector:CONDucted?) will invoke the
alignment of the RF Preselector on Conducted Band and return a success or failure value. Successful
Preset: This is unaffected by Preset but is set to the factory setting on a “Restore
System Defaults->Align”.

Backwards Compatibility SCPI: :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.
Initial S/W Revision: Prior to A.02.00
Remote Command: :CALibration:FREQuency:REFerence:COARse <integer>
:CALibration:FREQuency:REFerence:COARse?
Example: :CAL:FREQ:REF:COAR 8191
Notes: 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.
