SYSTem Subsystem
The SYSTem subsystem supplies information and status about the SCPI command parser
and allows control over the instrument's front panel.
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 0, "No error"
until another error occurs. A table of possible errors is shown below.
Query Response
<integer>, <string> (ex. –104, “Data type error”)
