that is defined in IEEE488.2,11.5.1.1.4.
-101 Invalid character
Invalid characters exist in the program message string. For example, for a correct program
message, "MEAS
IRIM," an ampersand (&) is inserted by mistake, like "MEAS&IRIM".
-102 Syntax error
There is a command or data type that cannot be recognized. For example, though the
4294A did not accept any strings, a string was received.
-103 Invalid separator
The parser (syntax analysis program) expected a separator, but a character other than a
separator was sent. For example, though the correct way is using ";" to separate 2 sent
program messages like "MEAS IRIM;FMT LOGY", a semicolon (;) to separate the program
messages is missing, like "MEAS IRIM FMT LOGY".
-104 Data type error
The parser recognized impossible data elements. For example, numeric value or string data
was expected, but block data was sent.
-105 GET not allowed
A group execution trigger (GET) was received in a program message. (Refer to
IEEE488.2,7.7.)
-108 Parameter not allowed
The number of parameters is larger than that the command requires. For example, though
the "POIN" command requires 1 parameter like "POIN 101," 2 parameters are added like
"POIN 101,1."
-109 Missing parameter
The number of parameters is less than that the command requires. For example, though the
"POIN" command requires 1 parameter like "POIN 101," no parameter is added like
"POIN."
-111 Header separator error
The header separator is wrong.
This error is displayed when a character other than a defined header follows the header. For
example, when, though "*SRE 4" is correct, a character follows the header without a space
like "*SRE4", this error is displayed.
-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 defied for the 4294A was received. For example, "*XYZ" not defined for the
4294A was received.
-114 Headers Suffix out of range
The suffix of the header is out of range. The suffix of a numeral parameter that follows the
SCPI command makes the header invalid.
-120 Numeric data error
