Remarks
Module events are retrieved in first-in-first-out (FIFO) order and are cleared when you read them. The first event returned is the first event that was stored.
Up to 20 events can be logged in the module event queue. If more than 20 events are detected, they will be lost (only the first 20 events are saved).
Most of the plug-in modules have defined events that are logged in the event queue. For module-specific event definitions, see Plug-In Module Event Register Information.
The module event queue is cleared by the *CLS (Clear Status) command and when power is cycled. The events are also cleared when you read the module event queue. The module event queue is not cleared by a Factory Reset (*RST command) or an Instrument Preset (SYSTem:PRESet command).
Return Format
This command returns an ASCII string enclosed in double quotes. One string is returned each time this command is executed. If no events have been detected, a null string ( " " ) is returned. The command reads the event data and clears one event from the queue.
