System SourceMeter® Instrument Reference Manual Section 7:

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

status.request_enable
This attribute stores the service request (SRQ) enable register.
Type TSP-Link accessible Affected by Where saved Default value
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
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.
