Bit Value Description
B0 Not used Not applicable.
B1
status.operation.sweeping.SMUA
Set bit indicates that SMU A is sweeping.
Bit B1 decimal value: 2
Binary value: 0000 0010
B2-B5 Not used Not applicable.
In addition to the above constant, operationRegister can be set to the decimal equivalent of the bit to set.
Example
status.operation.sweeping.enable =
status.operation.sweeping.SMUA
Uses a constant to set the SMUA bit
of the operation status sweeping
summary enable register.

Operation Status Registers (on page E-9)
status.operation.*
(on page 7-265)
status.operation.trigger_overrun.*
This attribute contains the operation status trigger overrun summary register set.
Type TSP-Link accessible Affected by Where saved Default value

.condition (R) Yes Not applicable Not saved Not applicable
.enable (RW) Yes Status reset Not saved 0

Usage
operationRegister = status.operation.trigger_overrun.condition
operationRegister = status.operation.trigger_overrun.enable
operationRegister = status.operation.trigger_overrun.event
operationRegister = status.operation.trigger_overrun.ntr
operationRegister = status.operation.trigger_overrun.ptr
status.operation.trigger_overrun.enable = operationRegister
status.operation.trigger_overrun.ntr = operationRegister
status.operation.trigger_overrun.ptr = operationRegister
operationRegister
The status of the operation status trigger overrun 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 operation status trigger overrun 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 1.02600e+03 (which is 1,026) is read as the value of the condition register, the binary equivalent is
0000 0100 0000 0010. This value indicates that bit B1 and bit B10 are set.
