Error messages
Error number: -121
-121 Invalid character in number
An invalid character for the data type of the syntax analysis target is received. For example,
alphabetical characters exist in a decimal value or “9” exists in octal data.
-123 Exponent too large
The absolute value of the exponent exceeds 32,000. (Refer to IEEE488.2,7.7.2.4.1.)
-124 Too many digits
The number of digits of the mantissa of the decimal value data element exceeds 255 except
for preceding 0s. (Refer to IEEE488.27.7.2.4.1.)
-128 Numeric data not allowed
A numeric value data element (that does not violate the standard) is received where the
4287A does not accept any numeric value data element.
-131 Invalid suffix
The suffix does not meet the syntax defined in IEEE488.2,7.7.3.2 or is inappropriate for
the 4287A.
-134 Suffix too long
The suffix contains notation of 12 characters or more. (Refer to IEEE488.2,7.7.3.4.)
-138 Suffix not allowed
A suffix is added to a numeric value element that does not permit a suffix.
-148 Character data not allowed
A character data element (that does not violate the standard) is received where the 4287A
does not accept any character data element.
-150 String data error
An error not included in error numbers between -151 and -159 occurs during the syntax
analysis of a string data element.
-151 Invalid string data
Character string data are expected, but the string data received are invalid for some reason.
(Refer to IEEE488.2,7.7.5.2.) For example, the END message is received before the end
quotation mark character appears.
-158 String data not allowed
A string data element is received where the 4287A does not accept any string data element.
For example, a parameter must be enclosed with double quotation marks (“...”) but they are
missing.
-161 Invalid block data
Block data are expected, but the block data received are invalid for some reason. (Refer to
IEEE488.2,7.7.6.2.) For example, the END message is received before the length of the
block data is reached.
-168 Block data not allowed
A block data element is received where the 4287A does not accept any block data element.
