System
When Auto Align, Off is selected the Settings Panel indicates ALIGN OFF with a warning icon. The
warning icon is to inform the operator that they are responsible for maintaining the warranted
operation of the instrument:
Key Path System, Alignments, Auto Align
Mode All
Example :CAL:AUTO OFF
Notes Auto Align Off begins the elapsed time counter for Auto Align Off time.
Couplings Auto Align is set to Off if Restore Align Data is invoked.

All but RF
Auto Align, All but RF, configures automatic alignment to include or exclude the RF subsystem.
(Eliminating the automatic alignment of the RF subsystem prevents the input impedance from
changing. The normal input impedance of 50 ohms can change to an open circuit when
alignments are being used. Some devices under test do not behave acceptably under such
circumstances, for example by showing instability.) When Auto Align, All but RF ON is selected,
the operator is responsible for performing an Align Now, RF when RF-related alignments expire.
The Auto Align, Alert mechanism will notify the operator to perform an Align Now, All when the
combination of time and temperature variation is exceeded.
When Auto Align, All but RF ON is selected the Settings Panel indicates ALIGN AUTO/NO RF with
a warning icon (warning icon is intended to inform the operator they are responsible for the
maintaining the RF alignment of the instrument):
Key Path System, Alignments, Auto Align
Mode All
Remote Command :CALibration:AUTO:MODE ALL|NRF
:CALibration:AUTO:MODE?
Example :CAL:AUTO:MODE NRF
Preset This is unaffected by Preset but is set to ALL on a “Restore System Defaults->Align”.
State Saved No
