Time & Temperature Light
SCPI Example
CAL:AUTO:ALER LIGH
This is a light version of Time & Temperature which means for this setting the
time/temperature changes required to trigger an alert are increased by a factor of
three and the time alerts will occur one-ninth as often as for Time and Temperature.
24 hours
SCPI Example
CAL:AUTO:ALER DAY
The instrument signals an alert after a time span of 24 hours since the last
successful full alignment (for example, Align Now All or completion of a full Auto
Align). You may want to select this option in an environment where the temperature
is stable on a daily basis, at a small risk of accuracy errors in excess of the warranted
specifications. The alert is the Error Condition message “Align Now All required”.
7 days
SCPI Example
CAL:AUTO:ALER WEEK
The instrument signals an alert after a time span of 168 hours since the last
successful full alignment (for example, Align Now All or completion of a full Auto
Align). You may want to select this option in an environment where the temperature
is stable on a weekly basis, at a modest risk of accuracy degradations in excess of
warranted performance. The alert is the Error Condition message “Align Now All
required”.
None
SCPI Example
CAL:AUTO:ALER NONE
The instrument does not signal an alert. This is provided for rare occasions where
you are making a long measurement that cannot tolerate Auto Align interruptions,
and must have the ability to capture a screen image at the end of the measurement
without an alert posted to the display. Keysight does not recommend using this
selection in any other circumstances, because of the risk of accuracy performance
drifting well beyond expected levels without the operator being informed.
4.6.2 Align Now
Accesses alignment processes that are immediate action operations. They perform
complete operations and run until they are complete.
Executing immediate alignments from SCPI can be problematic due to the length of
time required for the alignments to complete. Alignment commands are by their
