Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz 485
There are 2 very quick alignments, invisible to the user, that are done every few minutes or
when certain settings are changed. These still occur, even if AutoAlign is set to Off. These
alignments are the Current SysGain and Current IF Flatness methods which can also be
forced to occur by user under the Align Subsys menu.

State Saved: Survives Preset and power cycle, but not saved in Instrument State.
Remote Command:
:CALibration:AUTO OFF|ON|ALERt
:CALibration:AUTO?
Example:
CAL:AUTO ON
Align All Now
Immediately executes an alignment cycle of all the subsystems (Align RF, Align IF, Align
ADC, and Align Current Sys Gain). The instrument will stop any measurement currently
underway, perform the full alignment, then restart the measurement from the beginning
(similar to pressing the Restart key). All other operations are stopped and the alignments
will be visible on the display.
Key Path: System, Alignments
Remote Command:
:CALibration[:ALL] Performs a full alignment.
The following three commands perform a full alignment and return a number indicating the
success of the alignment. A zero is returned if the alignment is successful. A one is
returned if any part of the alignment fails.
:CALibration[:ALL]?
*CAL?
*TST?
Example:
CAL? The query performs a full alignment and returns a number indicating the success of
the alignment. A zero is returned if the alignment is successful.
