Alignments
Accesses the following Alignments menu keys which align the internal
circuitry of the analyzer, load default values for the alignment system,
and adjust the 10 MHz reference.
Key Access:
System
Auto Align
Accesses the Auto Align menu keys.
All Turns on the automatic alignment of all
measurement systems. When
Auto
Align
, All is selected, “AA” appears along
the left edge of the display.
Key Access:
System, Alignments
All but RF
Turns on the automatic alignment of all
measurement systems except the RF
section. (Eliminating automatic
alignment of the RF prevents changes
in the input impedance between
sweeps, which could cause input device
instability.) When
Auto Align, All but RF
is selected, “
AB” appears along the left
edge of the display.
Key Access:
System, Alignments
Off
Turns off automatic alignment.

NOTE It is normal to hear clicking sounds when the Auto Alignment function
is On. During retrace, a small portion of the analyzer circuitry is
realigned. Some of the switching of the analyzer circuitry is done using
relays. It is the rapid switching of these relays during retrace that
causes the clicking sounds. To eliminate the clicking sounds, turn the
auto alignment off by pressing
System, Alignments, Auto Align, Off.
When this is done, the Align Now, All function should be performed
periodically. Refer to the appropriate “Specifications and
Characteristics” chapter in the Agilent Technologies EMC Analyzers
Specifications Guide for more information on how often to perform Align
Now, All when the auto alignment is off
