Details
These attributes are used to read or write to the questionable status over temperature 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 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
B1
status.questionable.over_temperature.SMUA
Set bit indicates that an over temperature
condition was detected on SMU A.
Bit B1 decimal value: 2
Binary value: 0000 0010
B2
status.questionable.over_temperature.SMUB
This bit is only available on Models
2602B/2604B/2612B/2614B/2634B/2636B. Set
bit indicates that an over temperature condition
was detected on SMU B.
Bit B2 decimal value: 4
As an example, to set bit B1 of the questionable status over temperature summary enable register,
set
status.questionable.instrument.enable = status.questionable.instrument.SMUA
.
In addition to the above constants, questionableRegister can be set to the numeric equivalent of
the bit to set. To set more than one bit of the register, set operationRegister to the sum of their
decimal weights. For example, to set bits B1 and B2, set questionableRegister to 6 (which is
the sum of 2 + 4).
Example
status.questionable.over_temperature.enable =
status.questionable.over_temperature.SMUA
Uses a constant to set the SMU A
bit in the questionable status over
temperature summary enable
