For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to Status register set
contents (on page 15-1) and Enable and transition registers (on page 15-19). The individual bits of
this register are defined in the following table.
Bit
Value and description
B0 to B7
Not used
B8
status.questionable.instrument.smua.CALIBRATION
status.questionable.instrument.smua.CAL
Set bit indicates that the calibration constants stored in nonvolatile memory were corrupted and
could not be loaded when the instrument powered up.
Bit B8 decimal value: 256
B9
status.questionable.instrument.smua.UNSTABLE_OUTPUT
status.questionable.instrument.smua.UO
Set bit indicates that an unstable output condition was detected.
Bit B9 decimal value: 512
B10 to B11
Not used
B12
status.questionable.instrument.smua.OVER_TEMPERATURE
status.questionable.instrument.smua.OTEMP
Set bit indicates that an over temperature condition was detected.
Bit B12 decimal value: 4,096
B13 to B15
Not used
As an example, to set bit B8 of the questionable status SMU A summary enable register, set
status.questionable.instrument.smua.enable =
status.questionable.instrument.smua.CAL.
In addition to the above constants, questionableRegister can be set to the decimal value of the
bit to set. To set more than one bit of the register, set questionableRegister to the sum of their
decimal values. For example, to set bits B8 and B9, set questionableRegister to 768 (which is
the sum of 256 + 512).
