IMPORTANT NOTICE
Using Password Protection with the 8003
The Giga-tronics 8003 Precision Scalar Analyzer is shipped from the factory with the password protection feature OFF.
Password protection can be user activated to prevent unauthorized changes in the Cal Factor and Calibrator data stored
in the EEPROMs in the 8003 and sensors used with the instrument. It is strongly recommended that this password
protection be implemented immediately to prevent any problems that could arise due to accidental or unintentional
changes to the calibration data stored in the EEPROMs. Use the following procedure to activate the password protection
for the sensors and/or bridge:
1. Since the password is stored directly in the EEPROM physically contained in the housing of each sensor, attach the
sensor(s) to be protected to the A, B and/or C connections on the front panel of the 8003.
2. After the 8003 has been turned on, press the CONFIG key on the front panel.
3. The display will present the primary CONFIG menu. Press the SERVICE softkey at the bottom of the menu.
4. Press the SENSOR EEPROM softkey of the next menu presented.
5. A menu will then be displayed showing a choice of sensors A, B or C. Each sensor must be individually password
protected. Either the same or different passwords can be used for each individual sensor.
6. Assuming that sensors are attached to all 3 inputs, press the SENSOR A EEPROM softkey. (If sensors are not
connected to all 3 inputs, repeat the procedure that follows for just the sensors being used.)
7. Press the PA S SWD softkey of the next menu presented, and then press the DEFINE PASSWD softkey of the menu
that follows.
8. After the DEFINE PASSWD softkey has been pressed. a prompt will be displayed asking for a password. Six
number keys (the selected password sequence) should then be pressed. These keys will not be shown on the
screen.
9. Once the six number keys have been pressed, the display will again present a prompt asking that the password just
defined be entered again for confirmation. When the password has been confirmed, the defined password will then
be accepted.
10. Then press RETURN and PROGRAM EEPROM to store the password in the sensor EEPROM. From this point on,
the password must be entered before any calibration data can be changed in the sensor EEPROM.
11. Start with Step 6 for the next sensor to be protected.
For further information on accessing the softkeys used to store a password in the sensor EEPROM, see pages 2-64 and
2-65 in the OPERATION chapter (Operation Manual).
1. The following procedure should be used to activate password protection for the calibrator in the 8003.
2. Press the CONFIG key on the front panel, and then press the SERVICE softkey at the bottom of the primary
CONFIG menu.
3. Press the SET CAL softkey at the top of the next menu presented.
The next menu will contain a softkey label called DEFINE PASSWD. The DEFINE PASSWD softkey is used to define a
password that future users will have to enter in order to change the calibrator output. When this softkey is pressed, a
prompt is presented asking for a new password. Six number keys (the selected password sequence) should then be
pressed. The keys being pressed will not be shown on the screen. Once the six number keys have been pressed, the
display will again present a prompt asking that the password just defined be entered again to confirm the password.
When the password is confirmed, the defined password will be enabled.
(The CLEAR PASSWD softkey in the same menu as above is used to clear the password. Once this softkey is pressed,
the password will be cleared and future users will be able to adjust the calibrator output without having to know a
password until one is assigned again).
Further information on accessing the softkeys used in setting the calibrator output is given on page 2-61 in the
OPERATION chapter (Operation Manual).
NOTE: Sensors can be moved from one instrument to another, and will still retain their password
protection.
NOTE: Jumper W1 on the Calibrator Board must be moved to pins 2 and 3 from pins 1 and 2 to complete
the enabling of password protection.
