SYSTem:ERRor[:NEXT]?
(Query)
To the question SYST:ERR?, the instrument returns the number of error positioned at the top
of the queue. The queue has a stack of 20 numbers and is managed as follows :
first in, first out.
As the SYST:ERR? questions arrive, the instrument returns the number of errors in order of
arrival, until the queue is empty. Every more SYST:ERR? question involves a negative answer:
character "0" (ASCII 48code). If the queue is full, the case at the top of the queue takes the
value -350 (saturated queue).
The queue is empty:
- when the instrument is getting started.
- at the receipt of a *CLS.
- at the reading of the last error.
