Register. Used summary bits for this register include B1 (SMUA) and B2 (SMUB).
A set bit indicates that a SMU (A or B) is calibrating.
Operation Status Measurement Summary
This measurement summary register set feeds to MEAS bit B4 of the Operation
Status Register. Used summary bits for this register include B1 (SMUA) and B2
(SMUB). A set bit indicates that a SMU (A or B) is performing an overlapped
measurement.
Operation Status SMU A Summary Register
This SMU summary register set feeds to bit B1 (SMUA) of the Operation Status
Instrument Summary Register. Used summary bits for this register include B0
(CAL), B4 (MEAS), B11 (PRMPT), B12 (USER) and B14 (PROG). A set bit
indicates that the corresponding operation event for SMU A has occurred.
Operation Status SMU B Summary Register
This SMU summary register set feeds to bit B1 (SMUB) of the Operation Status
Instrument Summary Register. Used summary bits for this register include B0
(CAL), B4 (MEAS), B11 (PRMPT), B12 (USER) and B14 (PROG). A set bit
indicates that the corresponding operation event for SMU B has occurred.
Operation Status Instrument Summary Register
This summary register is fed from the SMU summary registers and then feeds to
bit B13 (INST) of the Operation Status Summary Register. Used summary bits for
Bit B0, Calibrating (CAL) — Set bit indicates that one or more channels
are calibrating.
Bit B4, Measuring (MEAS) — Bit will be set when taking an overlapped
measurement, but it will not set when taking a normal synchronous
measurement.
Bit B11, Prompts Enabled (PRMPT) — Set bit indicates that command
prompts are enabled.
Bit B12, User (USER) — Set bit indicates that an enabled bit in the
