Programming Guide
The calibration values are stored in non-volatile memory, and are unaffected
by power-on, save/recall, and *RST.
Use :DIAG:CAL:STAT? to check for successful calibration.
After calibration is completed, the state of this command' s parameter is OFF.
*RST: ON
Use :DIAG:CAL:STAT? to check for successful calibration.
After ONCE calibration is completed, the state of this command' s parameter
is OFF.
When :DIAG:CAL:INT is set to OFF, the Counter reports the positive status
condition (questionable Time, Frequency, and Phase) to bits 2, 5, and 6 of the
Questionable Status Register. When :DIAG:CAL:INT is set to ON, the
Counter reports the negative status condition (NOT questionable Time,
Frequency, and Phase) to bits 2, 5, and 6 of the Questionable Status Register.
