Error Messages
Error Messages (Order of Error Number)
-101 Invalid character
Invalid characters have been found in the program message string. For
example, in a correct program message ":CALC1:FORM CP", an ampersand (&)
is inserted by mistake to give ":CALC1:FORM&CP".
-102 Syntax error
There is a command or data type that cannot be recognized. For example, in
the program message ":SYST:PRES", a colon (:) is inserted by mistake to give
":SYST::PRES".
-103 Invalid separator
The parser (syntax analysis program) expects a separator, but a character
other than a separator has been sent. For example, although the correct way is
to use ";" to separate two sent program messages such as ":CALC1:FORM
CP;*OPC?", the semicolon (;) needed to separate the program messages is
missing to give ":CALC1:FORM CP *OPC?".
-104 Data type error
The parser has recognized impossible data elements. For example, numeric
value or string data is expected, but block data is sent.
-105 GET not allowed
A group execution trigger (GET) has been received in a program message.
(Refer to IEEE488.2,7.7.)
-108 Parameter not allowed
The number of parameters is larger than required by the command. For
example, although the :CREJ:LIM command requires one parameter such as
":CREJ:LIM 3", two parameters are added to give ":CREJ:LIM 0,3".
-109 Missing parameter
The number of parameters is less than required by the command. For example,
although the :CREJ:LIM command requires one parameter such as
":CREJ:LIM 3", no parameter is added to give ":CREJ:LIM".
-112 Program mnemonic too long
The length of the header exceeds 12 characters. (Refer to IEEE488.2,7.6.1.4.1.)
-113 Undefined header
A header not defined for the E4981A has been received. For example, "*XYZ",
which is not defined for the E4981A, is received.
-114 Header suffix out of range
The header suffix is out of range.
-120 Numeric data error
Numeric data is improper.
