SYSTem:ERRor?
This command queries the earliest entry in the error queue, and deletes it after the readout.
Positive error numbers indicate device-specific errors, negative error numbers are error messages
defined by SCPI (cf. chapter “Error Messages”). If the error queue is empty, the error number 0, "no
error", is returned. This command is identical with the command STATus:QUEue:NEXT?.

Example: "SYST:ERR?"
Characteristics: *RST value: –
SCPI: conform
Mode: R, A
SYSTem:ERRor:LIST?
This command reads all system messages and returns a list of comma separated strings. Each string
corresponds to an entry in the table SYSTEM MESSAGES.
If the error list is empty, an empty string "" will be returned.
This command is a query and therefore has no *RST value.
Example: "SYST:ERR:LIST?"
Characteristics: *RST value: –
SCPI: device-specific
Mode: R, A
The best performance is obtained when the display output is switched off during
remote control.
