Introduction

This section provides the complete Calibration Adjustment procedure for the Test
Tool.
The Test Tool allows closed-case calibration with known reference sources. It
measures the reference signals, calculates the correction factors, and stores the
correction factors in RAM. When the calibration is complete, the correction
factors can be stored in FlashROM.
The Test Tool should be calibrated after repair or if it fails the Performance
Verification. The Test Tool has a normal calibration cycle of one year.
Because the hardware and firmware has changed over the life of the Product,
development of a second version of the adjust procedure has been necessary.
This section has both adjust procedures.
To identify the procedure version you need:
1. Check that the serial number is 25375604 or higher. If yes, use the first
procedure.
2. If no, evaluate the firmware and Subversion. Press in sequence, USER, F3
VERSION & CAL. If the firmware version is V11.00 or lower, use the second
procedure.
If the firmware is V11.10 or higher:
3. In the same popup menu, check under Subversions that the last datablock is
x5xx (for instance 2516). This value determines the higher frequency adjust
point that should be used.
In the tables when red or blue values are listed:
•
5: The Final Calibration for V11.10 and later procedure should be done.
Use the levels in Red.
•
2: The Final Calibration for V11.10 and later procedure should be done.
Use the levels in Blue.
