Error
Number String
-148 "Character data not allowed"
[A legal character data element was encountered where prohibited by the device.]
-150 "String data error"
[This error, as well as errors -151 through -159, are generated when parsing a string data element.
This error message is used when the device cannot detect a more specific error.]
-151 "Invalid string data"
[A string data element was expected, but was invalid for some reason (see IEEE 488.2, 7.7.5.2); for
example, an END message was received before the terminal quote character.]
-158 "String data not allowed"
[A string data element was encountered but was not allowed by the device at this point in parsing.]
-160 "Block data error"
-161 "Invalid block data"
[A block data element was expected, but was invalid for some reason (see IEEE 488.2, 7.7.6.2); for
example, an END message was received before the length was satisfied.]
-168 "Block data not allowed"
[A legal block data element was encountered but was not allowed by the device at this point in
parsing.]
-170 "Expression error"
[This error, as well as errors -171 through -179, are generated when parsing an expression data
element. This particular error message is used when the device cannot detect a more specific
error.]
-171 "Invalid expression"
[The expression data element was invalid (see IEEE 488.2, 7.7.7.2); for example, unmatched
parentheses or an illegal character.]
-178 "Expression data not allowed"
[A legal expression data was encountered but was not allowed by the device at this point in
parsing.]
-180 "Macro error"
-181 "Invalid outside macro definition"
[Indicates that a macro parameter placeholder ($<number) was encountered outside of a macro
definition.]
-183 "Invalid inside macro definition"
[Indicates that the program message unit sequence, sent with a *DDT or *DMC command, is
syntactically invalid (see IEEE 488.2, 10.7.6.3).]
-184 "Macro parameter error"
