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 12-1) and Enable and transition registers (on page 12-19). The individual bits of
this register are defined in the following table.

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
