Error Error Description [description/explanation/examples]
Number
-100 Command error
This is the generic syntax error for devices that cannot detect more
defined in IEEE 488.2, 11.5.1.1.4 has occurred.
-101 Invalid character
A syntactic element contains a character which is invalid for that
type; for example, a header containing an ampersand, SETUP&.
This error might be used in place of errors - 114, - 12 1, - 14 1, and
perhaps some others.
-102
Syntax error
An unrecognized command or data type was encountered; for
example, a string was received when the device does not accept
strings.
-103 Invalid separator
The parser was expecting a separator and encountered an illegal
character; for example, the semicolon was omitted after a program
message unit, *EMC 1 :CHl:VoLTS 5.
-104 Data type error
The parser recognized a data element different than one allowed;
for example, numeric or string data was expected but block data
was encountered.
GET not allowed
-105
A Group Execute Trigger was received within a program message
(see IEEE 488.2, 7.7). Correct the HP-IS controller program so that
the group execute trigger does not occur within a line of HP-IB
program code.
-108 Parameter not allowed
More parameters were received than expected for the header; for
example, the *EMC common command only accepts one parameter,
so receiving *EMC 0,l is not allowed.
