Adjustment Program; Adjustment Program Flow - Agilent Technologies 4349B Service Manual

Adjustment Program

The adjustment program listed in Table 1-1 is required for the adjustments. Using the program,
the computer controls the 4349B and the other pieces of equipment to obtain the adjustment
data, and stores the data in the 4349B's internal EEPROM, A2U1.
The adjustment program runs on the computer listed in Table 1-1. The program should be
installed into your computer according to the procedure described in \Program Installation". To
start the program after it has been installed, refer to \Program Execution".
Figure 2-1 shows the adjustment program ow. The following lists the brief explanation for
each menu item. At the end of each adjustment, the program writes the obtained adjustment
data both to the 4349B internal EEPROM and to the unit-serial-number dependent le on the
disk.
