Device Specific Errors
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
firmware condition. These codes are also used for
self-test response errors. 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. 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.
The string is not optional; if the designer does not
wish to implement a string for a particular error, the
null 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-specific errors shall not generate
command errors, execution errors, or query errors; see
the other error definitions in this section.
Indicates that some error, termed “system error”
by the device, has occurred. This code is device-
dependent.
