SCPI Commands
SYST:ERR?
The error queue query message is a request for the next entry from the
instrument’s error/event queue. Items in this queue contain an integer in the

descriptive text. Negative numbers are reserved by the SCPI standard; positive
numbers are instrument-dependent. A value of zero indicates that no error or
event has occurred.
