If the queue is empty, the response is
0,"No error"
Positive error numbers are instrument-dependent. Negative
error numbers are reserved by the SCPI standard.
Volatile errors are reported once, at the time they appear. Identi-
cal errors are reported repeatedly only if the original error has
already been retrieved from (and hence not any more present in)
the error queue.
Example:
SYST:ERR:ALL?
Queries all entries in the error queue.
Response: 0, 'no error'
No errors have occurred since the error queue was last read out.
Usage:
Query only
:SYSTem:ERRor:CODE:ALL?

Return values:
<All>
string
