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:

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):

Alert
The instrument will signal an Alert when conditions exist such that you will need to perform a full alignment
(for example, Align Now, All). The Alert can be configured in one of four settings; Time & Temperature, 24
hours, 7 days, or None. A confirmation is required when a selection other than Time & Temperature is
chosen. This prevents accidental deactivation of alerts.
