5.2.2 Error Message
5.2.2.1 Command Error
This is a generic syntax error for devices that cannot detect more
specific errors. This code indicates only that a Command Error as
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, -121, -141, 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.
The parser was expecting a separator and encountered an illegal
character; for example, the semicolon was omitted after a program
message unit, *EMC 1:CH1: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.
A Group Execute Trigger was received within a program message (see
IEEE 488.2, 7.7).
-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, 1 is not allowed.
Fewer parameters were received than required for the header; for
example, the *EMC common command requires one parameter, so
receiving *EMC is not allowed.
