SYSTem Subsystem
The SYSTem subsystem { XE “Commands:SYSTem” } supplies information and status about
the SCPI command parser.
SYSTem Subsystem Functions
:ERRor?
Description
Reads error strings from the SCPI Error Queue. If the Error Queue has
any entries, the Error Queue bit is set in the Status Byte. The
instrument has a 30 entry, first-in, first-out queue. Repeatedly sending
the query :SYST:ERr? returns the error numbers and descriptions in
the order in which they occurred until the queue is empty. Any further
queries return "No error" until another error occurs. A table of possible
errors is shown below.
Query Response
<integer>, <string> (e.g., –104, “Data type error”)
