Adjustment Procedures
Individual Calib rations
To perform indi
vidual calibrations, click the calibration buttons, starting with
10MHz Reference..., and the corresponding calibrations are executed.
Execute All Calibrations
To perform all calibrations in one step, click Execute All Calibrations and all
calibration
s are executed in order starting from the top. Instead of performing all
the steps in the data timing calibration, restore and use the calibration constants
obtained b y the ATS (Auto Test System) at the factory or during servicing. The
following procedures assume that this method will be used.
Saving the Calibration
Results to EEPROM
When the calibration has been performed and the results are saved to the EEPROM
(regardless of the item, all results are saved to the EEPROM on the MIO board),
the flag under Is Calibrated will be set to TRUE. If the calibra tion was successful,
the Status field will display PASS. If the calibration failed, FAIL will be displayed.
There are two types of calibration: Self calibration and Manual calibration.
Self calibration - The instrument performs the calibration item a nd ends
automatically.
Manual calibration - This calibration item requires external test equipment
and manual data input. (See Table 3-2 on page 3-2.)
A warning message is displayed if you click a calibration button without waiting
for 20 minutes after the instrument powered on. Click the Cancel button and
allow at least 20 minutes for the instrument to warm up.
