STATus:OPERation:CONDition?
STATus:OPERation:CONDition? returns the state of the Condition
Register in the Operation Status Group. The state represents conditions
which are part of the instrument’s operation. The switch module driver
does not set bit 8 in this register (see STATus:OPERation[:EVENt]?).
