SCPI-Defined Errors
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.
Table 5-1. Command Errors (1 of 4)
Error Number Error Description [description/explanation/examples]
–101 desc = “Invalid character”
help = ““
[A syntactic element contains a character which is invalid for that type; for
example, a header containing an ampersand, SETUP&. This error might be used
in place of errors –114, –121, –141, and perhaps some others.]
–102 desc = “Syntax error”
help = ““
[An unrecognized command or data type was encountered for example, a sting
was received when the instrument does not accept strings.]
–103 desc = “Invalid separator”
help = ““
[The parser was expecting a separator and encountered an illegal character; for
example, the semicolon was omitted after a program message unit, *EMC
1:CH1:VOLTS 5.]
–104 desc = “Wrong Parameter Type”
help = ““
[The parser recognized a data element different than one allowed; for example,
numeric or string data was expected but block data was encountered.]
–105 desc = “GET not allowed”
help = ““
[A Group Execute Trigger was received within a program message (see
IEEE 488.2, 7.7).]
