Error Messages From -499 To -400
These error messages indicate that the Output Queue Control of
the synthesizer has detected a problem with the message exchange
protocol. This type of error sets the Query Error Bit (bit 2) in the
Event Status Register. One of the following has occurred:
n An attempt has been made to read data from the Output Queue
when no output is present or is pending.
w
Data in the Output Queue has been lost.
Events that generate Query Errors do not generate Command Errors,
Execution Errors, or Device-specific Errors.

These error messages indicate that some device operations did not
properly complete, possibly due to an abnormal hardware or firmware
condition. This type of error sets the Device-specific Error (bit 3)
in the Event Status Register. Events that generate Device-specific
Errors do not generate Command Errors, Execution Errors, or Query
Errors.

Error Messages From -299 To -200
These error messages indicate that an error has been detected by the
synthesizer’s Execution Control Block. An error of this type sets the
Execution Error Bit (bit 4)
in the Event Status Register. One of the
following events has occurred:
n A data element following a header was evaluated by the synthesizer
as outside of its legal input range or is inconsistent with the
synthesizer’s capability.
w
A valid program message can not be properly executed due to
some instrument condition.
Execution Errors are reported by the synthesizer after rounding
and expression evaluation operations have taken place. Errors
that generate Execution Errors do not generate Command Errors,
Device-specific Errors, or Query Errors.
