Overview
All Alignment
or
Align All Now
corrects for receiver drift over temperature and
time. SA measurement applications monitor changes in internal temperature
and the time since last alignment update and trigger the need for a new
update when the alignment becomes stale. The alignment is deemed stale
after a significant change in temperature or a significant time elapsed from the
last update. The temperature change and time duration necessary to trigger an
alignment update is predetermined in the factory. Until the update is
performed, annotation indicating “questionable amplitude” is displayed
AMPTD?
.
When
All Alignment
is enabled (by default) the FieldFox performs an
alignment process using the internal RF source. Although some sweeps are
delayed, measurement results are never disturbed.
If the Independent Source (tracking generator) is enabled for your
measurement, it will be borrowed to perform the alignment. Again, the
measurement results are not disturbed. Learn about the Independent Source in
“Independent Source/Tracking Generator ” on page 161
The alignment process can be disabled. You may want to do this, for example,
if you are analyzing the amplitude stability of a signal.
SA and all modes built on its infrastructure require three types of alignments:
— InstAlign Amplitude Alignment
To better reflect the enhancements implemented during the alignment
process, for firmware versions

A.10.15 "IF Flatness Alignment" is now
referred to as "Channel Equalization" or "Channel Equalization Alignment"
(
ChanEQ Alignment
).
