Periodic Adjustments

A Word About Storing Calibration Factors

You should understand the calibration-factor-storage process before

running any of the following programs: Periodic Calibration, IQ

Calibration, Eb/No 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.
