Table 2-5 lists SCPI commands used for input bias current and offset voltage calibration.
SCPI command input bias current calibration
1.
Connect a triax shielding cap to the rear panel INPUT jack. (Use a Keithley CAP-31 or
equivalent.)
2.
Send the following command to perform input bias current calibration:
:CAL:UNPR:IOFF
3.
Allow the Model 6514 to complete the calibration process.
SCPI command offset voltage calibration
1.
Connect a triax short to the rear panel INPUT jack. (Use the supplied Model 237-ALG-2
triax cable or equivalent with red and black alligator clips connected together.)
2.
Send the following command to perform offset voltage calibration:
:CAL:UNPR:VOFF
3.
Allow the Model 6514 to complete the calibration process.
