269
– An unrecognized header was received. Unrecognized headers include incorrect
instrument-specific headers and incorrect or unimplemented IEEE 488.2
Common Commands.
– A Group Execute Trigger (
GET
) was entered into the input buffer inside of an
IEEE 488.2 program message.
Events that generate command errors do not generate execution errors,
device-specific errors, or query errors.
Execution Error
An
<error number>
in the range [
–
200 to
–
299] indicates that an error has been
detected by the instrument's execution control block. The occurrence of any error
in this class causes the execution error bit (bit 4) in the Event Status Register to be
set. One of the following events has occurred:
– A
<PROGRAM DATA>
element following a header was evaluated by the
instrument as outside of its legal input range or is otherwise inconsistent with
the instrument's capabilities.
– A valid program message could not be properly executed due to some
instrument condition.
Execution errors are reported by the instrument after rounding and expression
evaluation operations have been taken place. Rounding a numeric data element,
for example, is not reported as an execution error. Events that generate execution
errors do not generate command errors, device-specific errors, or query errors.
Device-Specific or Instrument-Specific Error
An
<error number>
in the range [
–
300 to
–
399] or [+1 to +32767] indicates that
the instrument has detected an error that is not a command error,
a query error, or an execution error; some instrument 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 causes the device-specific error bit (bit 3)
in the Event Status Register to be set.
