Usage
questionableRegister = status.questionable.instrument.smuX.condition
questionableRegister = status.questionable.instrument.smuX.enable
questionableRegister = status.questionable.instrument.smuX.event
questionableRegister = status.questionable.instrument.smuX.ntr
questionableRegister = status.questionable.instrument.smuX.ptr
status.questionable.instrument.smuX.enable = questionableRegister
status.questionable.instrument.smuX.ntr = questionableRegister
status.questionable.instrument.smuX.ptr = questionableRegister
questionableRegister
The status of the questionable status SMU X summary register; a zero (0)
indicates no bits set (also send 0 to clear all bits); other values indicate various
bit settings
X
Source-measure unit (SMU) channel (for example
status.questionable.instrument.smua.enable applies to SMU
channel A)
Details
These attributes are used to read or write to the questionable status instrument SMU X summary registers.
Reading a status register returns a value. The binary equivalent of the returned value indicates which register
bits are set. The least significant bit of the binary number is bit B0, and the most significant bit is bit B15. For
example, if a value of 7.68000e+02 (which is 768) is read as the value of the condition register, the binary
equivalent is 0000 0011 0000 0000. This value indicates that bit B8 and bit B9 are set.

For information about .condition, .enable, .event, .ntr, and .ptr registers, refer to Status register set contents (on
page E-1) and Enable and transition registers (on page E-19). The individual bits of this register are defined in
the following table.
Bit Value Description
B0-B7
Not used
Not applicable.
B8
status.questionable.instrument.smuX.CALIBRATION
status.questionable.instrument.smuX.CAL
Set bit indicates that the
calibration constants
stored in nonvolatile

and could not be loaded
when the instrument
powered up.
Bit B8 decimal value: 256
B9

status.questionable.instrument.smuX.UO
Set bit indicates that an
unstable output condition
was detected.
Bit B9 decimal value: 512

Not used
Not applicable
B12
status.questionable.instrument.smuX.OVER_TEMPERATURE
status.questionable.instrument.smuX.OTEMP
Set bit indicates that an
over temperature condition
was detected.
Bit B12 decimal value:
4,096
B13-B15
Not used
