SCPI commands — calibration
Commands for calibration are listed in Tabl e 17 - 5. Additional information for each
command is provided in added notes and several tables that follow.
1. CAL:PROT:CODE “<string>” ‘ Enter password
This command sends the calibration password/code to unlock calibration. The
code is an eight-character string that must be enclosed in single or double
quotes. The Model 6220 default code is KI006220; the default Model 6221
code is KI006221. You can change the code once calibration is unlocked by
sending a different code with this command. However, if you change the first
two characters to something other than “KI”, you will not be able to unlock cal-
ibration from the front panel.
2. CAL:PROT:LOCK ‘ Lock out calibration
This command locks out calibration. Note that the CAL:PROT:LOCK? query
will return a 1 if calibration is locked; 0 otherwise.
