Details
When an event occurs on the instrument, it is placed in the event log. The
:SYSTem:EVENtlog:NEXT? command retrieves an unread event from the event log. Once an event
is read, it can no longer be accessed remotely. However, it can be viewed on the front panel.
To read multiple commands, execute this command multiple times.
If there are no entries in the event log, the following is returned:
0,"No error;0,0,0"
If the event type is not defined, an event of any type is returned.
Note that if you have used :SYSTem:ERRor[:NEXT]? to check events,
:SYSTem:EVENtlog:NEXT? shows the next event item after the last error that was returned by
:SYSTem:ERRor[:NEXT]? You will not see warnings or information event log items that occurred
before you used :SYSTem:ERRor[:NEXT]?
If the event type is not defined, an event of any type is returned.
The information that is returned is in the order:
<eventNumber>, <message>, <eventType>, <timeSeconds>, <timeNanoSeconds>
