HP-IB - Command Errors -101 -102 -103 Invalidseparator -104 -105 -108 -109 -111 -112 -113 Invalidcharacter 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 -121, -141, and perhaps some others. Syntax error An unrecognized command or data type was encountered. For example, a string was received when the device does not accept strings. Additional information is available over HP-IB. The parser was expecting a separator and encountered an illegal character. For example, the semicolon was omitted after a program unit, *EMCl:CHl:VOLTS5. Datatype error The parser recognized a data element different than one allowed. For example, numeric or string data was expected but block data was encountered. GETnot allowed A Group Execute Trigger was received within a program message (see IEEE 688.2.7.7). Parameternot allowed More parameters were received than expected for the header. For example, the *EMC common command only accepts one parameter, so receiving *EMCO,l is not allowed. Missingparameter Fewer parameters were received than required for the header. For example, the *EMC common command requires one parameter, so receiving *EMC is not allowed. Header separator error A character which is not a legal header separator was encountered while parsing the header. For example, no white space followed the header, thus *GMC“MACRO” is in error. Programmnemonictoolong The header contains more than twelve characters (see IEEE 488.2 7.6.1.4.1). Undefinedheader The header is syntactically correct, but it is undefined for this specific device. For example, *XYZ is not defined for any device. Operation Messages lc-5
