Error Message Types - Agilent Technologies ESA-E Series Programmer's Manual

Error Message Types

Events do not generate more than one type of error. For example, an
event that generates a query error will not generate a device-specific,
execution, or command error.
These errors indicate that the instrument output queue control has
–499 to –400:
Query Errors detected a problem with the message exchange protocol described in
IEEE 488.2, Chapter 6. Errors in this class set the query error bit (bit
2) in the event status register (IEEE 488.2, section 11.5.1). These errors
correspond to message exchange protocol errors described in IEEE
488.2, 6.5. In this case:
• Either an attempt is being made to read data from the output queue
• data in the output queue has been lost.
–299 to –200: These errors indicate that an error has been detected during
Execution Error instrument execution.
Messages
–199 to –100: These errors indicate that the instrument parser detected an IEEE
Command Errors 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
• an unrecognized header was received. These include incorrect
201 to 799: These errors indicate that a device operation did not properly complete,
possibly due to an abnormal hardware or firmware condition. These
Device-Specific
Errors 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 part of the SCPI
standard. A positive error indicates that the instrument detected an
error within the GPIB system, within the instrument firmware or
hardware, during the transfer of block data, or during calibration.

when no output is either present or pending, or
(a control-to-device message was received that is in violation of the
IEEE 488.2 standard. Possible violations include a data element
which violates device listening formats or whose type is
unacceptable to the device.), or
device-specific headers and incorrect or unimplemented IEEE 488.2
common commands.
