SYSTem:ERRor?
This command is used to query the error information of the instrument. When
the ERROR indicator on the front panel is lit, it indicates that one or more errors
have occurred in the hardware or command syntax of the detected instrument.
Up to 20 sets of error messages can be stored in the error queue. This
command is sent once to read an error message from the error queue.
⚫
The front-panel ERROR annunciator turns on when one or more errors are
currently stored in the error queue. Error retrieval is first-in-first-out (FIFO),
and errors are cleared as you read them. When you have read all errors
from the error queue, the ERROR annunciator turns off.
⚫
If more than 20 errors have occurred, the last error stored in the queue (the
most recent error) is replaced with -350 ("Error queue overflow"). No
additional errors are stored until you remove errors from the queue. If no
errors have occurred when you read the error queue, the instrument
responds with +0 ("No error").
⚫
If the instrument is turned off or the *CLS (clear status) command is sent,
the error message in the error queue will be cleared. The *RST command
will not clear the error message in the error queue.
The error code and error information are as follows.
(0) No error
(-102) Syntax error
(-103) Invalid separator
(-108) Parameter not allowed
(-109) Missing parameter
(-113) Undefined header
(-131) Invalid suffix
(-138) Suffix not allowed
(-200) Execution Error
(-222) Data out of Range
(-350) Queue overflow
SYSTem:CLEar
This command is used to clear the error queue.
