status.questionable.unstable_output.SMUB
This bit is only available on 2602B,
2604B, 2612B, 2614B, 2634B, 2636B.
Set bit indicates that an unstable output
condition was detected on SMU B.
Bit B2 decimal value: 4
Binary value: 0000 0100
As an example, to set bit B1 of the questionable status unstable output 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.unstable_output.enable =
status.questionable.unstable_output.SMUA
Uses a constant to set the SMU A bit in the questionable status unstable output summary enable register bit.

status.request_enable
This attribute stores the service request (SRQ) enable register.
Usage
requestSRQEnableRegister = status.request_enable
status.request_enable = requestSRQEnableRegister
The status of the service request (SRQ) enable register; a zero
(0) indicates no bits set (also send 0 to clear all bits); other values
indicate various bit settings
Details
This attribute is used to read or write to the service request enable register. Reading the service
request enable register returns a value. The binary equivalent of the value of this attribute indicates
which register bits are set. In the binary equivalent, the least significant bit is bit B0, and the most
significant bit is bit B7. For example, if a value of 1.29000e+02 (which is 129) is read as the value of
this register, the binary equivalent is 1000 0001. This value indicates that bit B0 and bit B7 are set.
