Usage
questionableRegister = status.questionable.over_temperature.condition
questionableRegister = status.questionable.over_temperature.enable
questionableRegister = status.questionable.over_temperature.event
questionableRegister = status.questionable.over_temperature.ntr
questionableRegister = status.questionable.over_temperature.ptr
status.questionable.over_temperature.enable = questionableRegister
status.questionable.over_temperature.ntr = questionableRegister
status.questionable.over_temperature.ptr = questionableRegister
operationRegister
The status of the questionable status over temperature summary register; a
zero (0) indicates no bits set (also send 0 to clear all bits); other values indicate
various bit settings
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
B0
Not used
Not applicable.
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
Binary value: 0000 0100
B3-B15 Not used Not applicable.
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
register.
