Error Codes			GPIB Error Strings
Table 18 Overview for Supported Strings
		Error
	New/Old/Standard	Number	String
	Standard	-150	“String data error”
			[This error, as well as errors -151 through -159, are generated when pars-
			ing a string data element. This error message is used when the device can-
			not detect a more specific error.]
	Standard	-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.]
	Standard	-158	“String data not allowed”
			[A string data element was encountered but was not allowed by the de-
			vice at this point in parsing.]
	Standard	-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.]
	Standard	-168	“Block data not allowed”
			[A legal block data element was encountered but was not allowed by the
			device at this point in parsing.]
	Standard	-170	“Expression error”
			[This error, as well as errors -171 through -179, are generated when pars-
			ing an expression data element. This particular error message is used
			when the device cannot detect a more specific error.]
	Standard	-171	“Invalid expression”
			[The expression data element was invalid (see IEEE 488.2, 7.7.7.2); for ex-
			ample, unmatched parentheses or an illegal character.]
	Standard	-178	“Expression data not allowed”
			[A legal expression data was encountered but was not allowed by the de-
			vice at this point in parsing.]
	Standard	-181	“Invalid outside macro definition”
			[Indicates that a macro parameter placeholder ($<number) was encoun-
			tered outside of a macro definition.]
	Standard	-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).]
