F
1070 Fan failed
Cooling fan hardware failure is detected.
Contact Keysight Technology’s Sales and Service Office or the company from which you
purchased the device.
G
-105 GET not allowed
A group execution trigger (GET) has been received in a program message. (Refer to
IEEE488.2,7.7.)
H
-114 Header suffix out of range
The header suffix is out of range.
I
-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
”.
-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?
”.
-121 Invalid character in number
An invalid character for the data type of the syntax analysis target has been received. For
example, alphabetical characters exist in a decimal value or “9” exists in octal data.
-131 Invalid suffix
The suffix does not meet the syntax defined in IEEE488.2,7.7.3.2 or is inappropriate for
the E4981A.
-141 Invalid character data
A character data element has been recieved where the E4981A does not accepts any
character 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.
