Error Message Description
-100
Command error This is the generic syntax error
-102
Syntax Error An unrecognized command or data type was
encountered; for example, a string was received when the device
does not accept strings.
-108
Parameter not Allowed More parameters were received than
expected for the header; for example, the *SRE common
command only accepts one parameter, so receiving *SRE 0,1 is
not allowed.
-109
Missing Parameter Fewer parameters were received than
required for the header; for example, the *SAV common
command requires one parameter, so receiving *SAV is not
allowed.
-110
Command header error An error was detected in the header.
-113
Undefined header The header is syntactically correct, but it is
undefined for this specific device; for example, *XYZ is not
defined for any device.
-121
Invalid character in number An invalid character for the data
type being parsed was encountered; for example, an alpha in a
decimal numeric or a “9” in octal data.
-140
Character data error This error is generated when parsing a
character data element.
-150
String data error This error is generated when parsing a string
data element fails.
-151
Invalid string data A string data element was expected, but was
invalid for some reason (see
IEEE 488.2,
7.7.5.2); for example,
an END message was received before the terminal quote
character.
