IF Flatness
This function turns the corrections related to IF flatness On or Off.
When IF Flatness is OFF, the Advisory Event "IF Flatness corrections OFF"
will be displayed.

Snapshot Alignments On/Off
During normal auto alignment operation, the firmware will perform an RBW
and IQ alignment when the analyzer RBW state is changed, and every 10
minutes thereafter. These alignments can hinder troubleshooting the
analyzer since they can change correction factors when the state is
changed. Turning snapshot alignments off disables the RBW portion of
these alignments for more accurate troubleshooting. (Use IF Flatness
ON/OFF to control the IQ alignment.)
When Snapshot Alignments are OFF, the Advisory Event "Snapshot OFF"
will be displayed.
When Snapshot Alignments are ON, the Advisory Event "Snapshot OFF"
will be cleared.

Response corrections OFF" will be cleared.
