Agilent Technologies 6834B Changing the Calibration Password, Saving the Calibration Constants

B - Verification and Calibration

Calibrating the Output Impedance (Agilent 6843A only)

NOTE: The output voltage and output current must be calibrated before the output impedance can be calibrated.

Action Display

32.Connect only the output impedance resistor across the output of the ac source. Do not connect any other equipment.

33. Press Shift Calibration, scroll to the CAL IMP command, and press Enter. CAL:IMP

34.Wait for the ac source to compute the output impedance calibration constant. The display returns to Meter mode when the calculation is complete.

The ac source is now holding the new impedance calibration constants in RAM

Saving the Calibration Constants

CAUTION: Storing calibration constants overwrites the existing ones in non-volatile memory. If you are not sure you want to permanently store the new constants, omit this step. The ac source calibration will then remain unchanged.

	mode. *RST and *RCL will also set the calibration state to OFF.

Changing the Calibration Password

The factory default password is 0. You can change the password when the ac source is in calibration mode (which requires you to enter the existing password). Proceed as follows:

	Action	Display
1.	Begin by pressing Shift Calibration and scrolling to the CAL ON command.	CAL ON 0.0

2.Enter the existing password from Entry keypad and press Enter

3. Press Shift Calibration and scroll to the CAL PASS command. CAL:PASS 0

4.Enter the new password from the keypad. You can use any number with up to six digits and an optional decimal point. If you want the calibration function to operate without requiring any password, change the password to 0 (zero).

NOTE: If you want the calibration function to operate without requiring any password, change the password to 0 (zero).
