Command Errors - Agilent Technologies 8712ET Programmer's Manual

Command Errors

An error/event number in the range −199 to −100 indicates that an IEEE
488.2 syntax error has been detected by the instrument's parser. The
occurrence of any error in this class shall cause the command error bit
(bit 5) in the event status register (IEEE 488.2, section 11.5.1) to be set.
One of the following events has occurred:
• An IEEE 488.2 syntax error has been detected by the parser. That is,
a controller-to-device message was received which is in violation of
the IEEE 488.2 standard. Possible violations include a data element
which violates the device listening formats or whose type is
unacceptable to the device.
• An unrecognized header was received. Unrecognized headers include
incorrect device-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 shall not generate execution
errors, device-specific errors, or query errors; see the other error
definitions in this chapter.
