Probable Cause
This error, as well as errors –151 through –159, are
generated when parsing a string data element. This
particular error message should be used if the
device cannot detect a more specific error.
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.
A string data element was encountered but was
not allowed by the device at this point in parsing.
This error, as well as errors –161 through –169, are
generated when parsing a block data element. This
particular error message should be used if the
device cannot detect a more specific error.
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.
A legal block data element was encountered but
was not allowed by the device at this point in
parsing.
This error, as well as errors –171 through –179, are
generated when parsing an expression data
element. This particular error message should be
used if the device cannot detect a more specific
error.
The expression data element was invalid (see IEEE
488.2, 7.7.7.2); for example, unmatched
parentheses or an illegal character.
A legal expression data was encountered but was
not allowed by the device at this point in parsing.
