Negative value
Negative error numbers denote error messages defined by
SCPI.
Example:
SYST:ERR:CODE
Queries the oldest entry in the error queue.
Response: 0
No errors have occurred since the error queue was last read out.
Usage:
Query only
:SYSTem:ERRor:COUNt?
Queries the number of entries in the error queue.
Return values:
<Count>
integer
0
The error queue is empty.
Example:
SYST:ERR:COUN
Queries the number of entries in the error queue.
Response: 1
One error has occurred since the error queue was last read out.
Usage:
Query only
:SYSTem:ERRor[:NEXT]?
Queries the error/event queue for the oldest item and removes it from the queue.
Return values:
<Next>
string
Error/event_number,"Error/event_description>[;Device-depend-
ent info]"
Error number and a short description of the error.
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?
Queries the oldest entry in the error queue.
Response: 0, 'no error'
No errors have occurred since the error queue was last read out.
Usage:
Query only
