Summary of Internal DAC Remote Calibration:
Set timeout for PC to be greater than 20 seconds.
Connect calibration voltage source to channel 1 (4.096 Volts DC).
Unlock security: CALibration:SECurity:STATe OFF, <code>
Read security state: CALibration:SECurity:STATe?
0 means OFF or unlocked.
Send the calibrate command: CALibration:VALue 4.096 (repeat
with CAL:VAL -4.096).
Send query command: CAL?.
Retrieve query result:
0 indicates the calibration PASSED.
Any value other than 0 indicates calibration FAILED.
If non-zero value, read error queue: SYSTem:ERRor?
Read errors until no more errors.
Consult the “Error Messages” section starting on page 163 for what
to do after receiving a specific calibration error message.
NOTE For a remote internal DAC calibration, DAC Cal is automatically
selected (over internal reference oscillator calibration) since the
cal value of 4.096 is smaller than the acceptable reference
oscillator frequency range.
NOTE An AutoCal is performed automatically after this calibration is
successfully completed.
