4.10.5.1 Command Errors
A command error is in the range -199 to -100, and indicates that a syntax error was detected. This
includes the case of an unrecognized header. The occurrence of a command error causes the CME bit
(bit 5) of the Standard Event Status Register to be set.
Code Description
-100 Command Error
-101 Invalid character
-102 Syntax error
-103 Invalid separator
-104 Data type error
-105 GET not allowed
-108 Parameter not allowed – More parameters than allowed were received
-109 Missing parameter – Fewer parameters than necessary were received
-110 Command header error
-111 Header separator error
-112 Program mnemonic too long – The mnemonic must contain no less than 12 characters
-113 Undefined header
-114 Header suffix out of range
-120 Numeric data error
-121 Invalid character in number
-123 Exponent too large – IEEE 488.2 specifies maximum of 32000
-124 Too many digits – IEEE 488.2 specifies maximum of 255 digits in mantissa.
-128 Numeric data not allowed – A different data type was expected
-131 Invalid suffix
-134 Suffix too long – A maximum of 12 characters are allowed in a suffix
-138 Suffix not allowed
-140 Character data error
-141 Invalid character data – Incorrect character data were received
-144 Character data too long – Character data may contain no more than 12 characters
-148 Character data not allowed
-158 String data not allowed
-168 Block data not allowed
-178 Expression data not allowed
4.10.5.2 Execution Errors
An execution error indicates that the device could not execute a syntactically correct command, either
since the data were out of the instrument's range, or due to a device condition. The EXE bit (bit 4) of
the Standard Event Status Register is set on occurrence of an execution error.
Code Description
-200 Execution error
-201 Invalid while in local – An attempt was made to change an instrument setting while the
instrument was in the LOCAL state
-211 Trigger ignored – The GET or *TRG common command was ignored due to the device
not being in the correct state to execute the trigger
-221 Settings conflict – The parameter is out of range due to the current instrument state
