Keysight E8402A, E8404A C-Size Mainframes User and Service Guide 113STATus Subsystem Programming the Enhanced MonitorSTATus:OPERation:EVENt?The STATus:OPERation:EVENt? query returns an integer representing the value ofthe event register for the operation status group.The event register latches positive transition events from the condition register. Apositive transition event will occur when a condition makes a transition from alow to a high state. Bits in the event register are latched, and once set, theyremain set until cleared by a STATus:OPERation:EVENt? query or *CLS (clearstatus). There is no buffering; so while an event bit is set, subsequent eventscorresponding to that bit are ignored. Event registers are read only.Events are queried in order to determine if transitions have occurred since thelast query. They do not indicate the current state (condition) of a particular event.Nor do they indicate how many times a transition has occurred.Returned DataComments– Refer to STATus:OPERation:CONDition? for a description of each bit in theOPERation status group.– Cleared by: *CLS, power-on, and by reading the register.Reset Condition*RST does not affect the status system, use *CLS to clear all event registers.Related CommandsSTATus:OPERation:CONDition?, STATus:OPERation:ENABle,*CLSType Range Default Descriptionint16 0 - 32767 none Bit mask indicating which events are set (1) or cleared (0) for theOPERation status group.
