Questionable Event Registers
As shown in
Event Status. Commands are summarized in
can also be set by using numeric parameter values. For details, see
ming enable and transition
For example, either of the following commands will set the CAL enable bit (B8):
status.questionable.enable = status.questionable.CAL
status.questionable.enable = 256
When reading a register, a numeric value is returned. The binary equivalent of this
value indicates which bits in the register are set. For details, see
ters" in this appendix. For example, the following command will read the
questionable enable register:
print(status.questionable.enable)
Questionable Status Register
This register set feeds to bit B3 (QSB) of the Status Byte. The bits used in the
Questionable Status Register set are described as follows:
•
•
•
Questionable Status Calibration Summary
This calibration summary register set feeds to CAL bit B8 of the Questionable
Status Register. Used summary bits for this register include B1 (SMUA) and B2
(SMUB). A set bit indicates that calibration for a SMU (A or B) is questionable.
Questionable Status Over Temperature Summary
This over temperature summary register set feeds to OTEMP bit B12 of the
Questionable Status Register. Used summary bits for this register include B1
(SMUA) and B2 (SMUB). A set bit indicates that an over temperature condition
was detected for a SMU (A or B).
Questionable Status SMU A Summary Register
This SMU summary register set feeds to bit B1 (SMUA) of the Questionable
Status Instrument Summary Register. Used summary bits for this register include
Figure D-4, there are six register sets associated with Questionable
registers" in this appendix.
Bit B8, Calibration (CAL) — Set bit indicates that calibration is
questionable.
Bit B12, Over Temperature (OTEMP) — Set bit indicates that an over
temperature condition was detected.
Bit B13, Instrument Summary (INST) — Set bit indicates that a bit in the
questionable instrument summary register is set.
