715 Self-calibration failed; Chan n, null DAC cal, convergence error
sub attenuator value dB
The internal null DAC calibration failed to converge on a value during
the internal cal. Self-cal has exited without changing the self-cal
constants. Run self-test to diagnose the cause of the problem.
720 Self-calibration failed; Chan n, offset DAC cal with attenuator,
convergence error
Self-calibration failed; Chan n, offset DAC cal no attenuator,
convergence error
The internal offset DAC calibration failed to converge on a value during
the internal cal. Self-cal has exited without changing the self-cal
constants. Run self-test to diagnose the cause of the problem.
850 Calibration error; set up is invalid
You have selected an invalid calibration setup number.
850 Calibration error; set up is out of order
Certain calibration steps require a specific beginning and ending sequence.
You may not enter into the middle of a sequence of calibration steps.
