• 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 operation status user
register is set.
• Bit B13, Instrument Summary (INST) — Set bit indicates that an enabled bit in the
operation status instrument summary register is set.
• Bit B14, Program Running (PROG) — Set bit indicates that a program is running.
Operation Status Calibration Summary
This calibration summary register set feeds to CAL bit B0 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 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 this register include B1 (SMUA)
and B2 (SMUB). A set bit indicates that an operation event has occurred for SMU A and/or SMU B.
Operation Status User Register
This register set is controlled exclusively by the user. This register set feeds to bit B12 (USER) of
the Operation Status Summary Register. Bits of the user event register are set by setting the
corresponding bits of the user enable register and the user condition register. For example, the
following code will set B1 (Bit 1) of the Operation Status User Register and B12 (USER) of the
Operation Status Register:
status.operation.user.enable = 2
status.operation.user.condition = 2
