Universal SCPI Error Messages
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:

nAn 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.

Error Messages From -399 To -300

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:

nA 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.
