-141 Invalid character data
A character data element has been recieved where E4981A does not accepts any character
data element.
-148 Character data not allowed
Character data not allowed for this operation.
-150 String data error
An error not included in the error numbers between -151 and -159 has occurred 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 has been received where the E4981A 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 has been received where the E4981A does not accept any block data
element.
-170 Expression error
An error not included in the error numbers between -171 and -179 has occurred during the
syntax analysis of equation data.
-171 Invalid expression
The equation data element is invalid. (Refer to IEEE488.2,7.7.7.2.) For example,
parentheses are not paired or a character violates the standard.
-178 Expression data not allowed
An equation data element has been received where the E4981A does not accept any
equation data element.
-200 Execution error
A comprehensive execution error has occurred for which the E4981A cannot detect further
details. This error code simply indicates the occurrence of an execution error that is defined
in IEEE488.2,11.5.1.1.5.
-211 Trigger ignored
A trigger command or trigger signal has been received and recognized by the E4981A, but
it is ignored due to the timing relationship with the E4981A. For example, this happens
when the E4981A’s trigger system is not in the Waiting for Trigger state.
