This error occurs when the embedded memory is insufficient to save the user property in
ECal module during the user definition ECal processing.
-161 Invalid block data
Block data has been expected, but the block data that appears is invalid for some reason
(see 7.7.6.2, IEEE488.2). The END message is received before the length of block data has
been filled, for example.

If the type of calibration is not specified or not correct when partial overwrite is executed
with the GPIB command, this error occurs. This error does not occur for operation with
front keys.
-101 Invalid character
An invalid character exists in the program message character string.
-141 Invalid character data
An invalid character is found in the character data element, or the parameter received is
not valid.
-121 Invalid character in number
A character that is invalid for the data type subject to syntactic analysis has been received.
For example, a letter is found in a decimal numeric value or a numeric character "9" in
octal data.
500 Invalid equation expression
This error occurs when the invalid equation is specified in the equation of the equation
editor.
501 Invalid equation label
This error occurs when the invalid equation label is specified in the equation of the
equation editor.
A space is not available for the equation label.
-171 Invalid expression
The expression-data element is invalid (see 7.7.7.2, IEEE488.2). Parentheses are not
paired, or illegal characters are used, for example.
-103 Invalid separator
The parser (a syntactic analysis program) had been expecting a delimiter, but a character
that is not a delimiter has been sent.
-151 Invalid string data
