Storing Calibration Factors

Storing Calibration Factors
You should understand the calibration-factor-storage process before running any of
the following programs: Periodic Calibration, IQ Calibration, IQ Demod Path
Calibration, or System Power Calibration.
As a program runs, calibration factors are computed and applied. When all the
calibration factors have been acquired, the program stops and asks if the user
wants the calibration factors to be stored. At this point, it should be emphasized
that the new calibration factors are now being used by the Test Set. If you do not
store them at this point, they will be used by the Test Set until the power is
switched off even though they have not been stored.
If you do not store the calibration factors but run another calibration program and
then store the calibration factors, the calibration factors from the previous program
will be stored along with the calibration factors just acquired unless the power is
cycled between the tests. Storing calibration factors copies the calibration factors
from volatile to non-volatile memory (that is, memory that is not erased when the
power is turned off).
Also, when storing calibration factors, be sure to wait for the message
Updating Flash Calibration Files... DO NOT Interrupt
Power! to disappear before continuing. Depending on the number of calibration
factors being stored, this may take several minutes.
