Adjustment Program - Agilent Technologies 4338B Service Manual

Adjustment Program

The adjustment program listed in Table 1-1 is required for the adjustment. Using the program,
the computer controls the 4338B to obtain the adjustment data, and stores the data in the
4338B 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.
INITIAL SETUP de nes the standards' calibration values. Update the standard's calibration
values if necessary.
Resistance obtains the data to adjust the actual measurement resistance to the
Measurement standards' value, and writes the data both to the 4338B internal EEPROM
Adjustment and to the unit-serial-number dependent le on the disk. This adjustment
should be performed if the Impedance Measurement Accuracy performance
test fails.
Rewrite EEPROM writes the adjustment data, which is stored in the unit-serial-number
dependent le, to the EEPROM.
Note
Make sure that the correct line frequency (50 or 60Hz) has been selected in the
\UUT: 4338B" window preceding the Main Menu. This selection will improve
the adjustment data accuracy.
