data in the output queue has been lost.
Device Specific Errors (–399 to –300, 201 to 703, and 800 to 810) indicate that a
device operation did not properly complete, possibly due to an abnormal hardware or
firmware condition. These codes are also used for self-test response errors. Errors in this
class set the device-specific error bit (bit 3) in the event status register (IEEE 488.2, section
11.5.1).
The <error_message> string for a positive error is not defined by SCPI. A positive error
indicates that the instrument detected an error within the GPIB system, within the
instrument’s firmware or hardware, during the transfer of block data, or during calibration.
Execution Errors (–299 to –200) indicate that an error has been detected by the
instrument’s execution control block. Errors in this class set the execution error bit (bit 4) in
the event status register (IEEE 488.2, section 11.5.1). In this case:
Either a <PROGRAM DATA> element following a header was evaluated by the device as
outside of its legal input range or is otherwise inconsistent with the device’s capabilities, or
a valid program message could not be properly executed due to some device condition.
Execution errors are reported after rounding and expression evaluation operations are
completed. Rounding a numeric data element, for example, is not reported as an execution
error.
Command Errors (–199 to –100) indicate that the instrument’s parser detected an
IEEE 488.2 syntax error. Errors in this class set the command error bit (bit 5) in the event
status register (IEEE 488.2, section 11.5.1). In this case:
• Either an IEEE 488.2 syntax error has been detected by the parser (a control-to-device
message was received that is in violation of the IEEE 488.2 standard. Possible violations
include a data element that violates device listening formats or whose type is
unacceptable to the device.), or
• An unrecognized header was received. These include incorrect device-specific headers
and incorrect or unimplemented IEEE 488.2 common commands.
