Details
These attributes are used to read or write to the questionable status calibration 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.calibration.SMUA
Set bit indicates that the SMU A calibration
constants stored in nonvolatile memory were
corrupted and could not be loaded when the
instrument powered up.
Bit B1 decimal value: 2
Binary value: 0000 0010
status.questionable.calibration.SMUB
This bit is only available on Models
2602B/2604B/2612B/2614B/2634B/2636B. Set bit
indicates that the SMU B calibration constants
stored in nonvolatile memory were corrupted and
could not be loaded when the instrument powered
up.
Bit B2 decimal value: 4
Binary value: 0000 0100
As an example, to set bit B1 of the questionable status calibration summary enable register, set
status.questionable.calibration.enable = status.questionable.calibration.SMU
A.
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.calibration.enable =
status.questionable.calibration.SMUA
Uses a constant to set the SMUA bit
of the questionable status calibration
