SCPI Error Messages
Device-specific
Error
An <error/event number> in the range
[
-399, -300
]
or [ 1, 32767
]
indicates that the instrument has detected an error which is not a command
error, a query error, or an execution error; some device operations did not
properly complete, possibly due to an abnormal hardware or
hrmware
condition. These codes are also used for self- test response errors. The
occurrence of any error in this class should cause the device-speciEc error bit
(bit 3) in the event status register (IEEE 488.2, section 11.5.1) to be set. The
meaning of positive error codes is device-dependent and may be enumerated
or bit mapped; the <error message> string for positive error codes
is not defined by SCPI and available to the device designer. Note that the
string is not optional; if the designer does not wish to implement a string
for a particular error, the nulI string should be sent (for example, 42,”
“).
The occurrence of any error in this class should cause the device-specific
error bit (bit 3) in the event status register (IEEE 488.2, section
11.5.1)
to be
set. Events that generate device-specihc errors shall not generate command
errors, execution errors, or query errors; see the other error dehnitions in this
section.
