Error Message 
 
Command Error 
 
A generic syntax error indicates that the device cannot detect more 
specific errors. This code indicates that only Command Error defined in 
IEEE 488.2,11.5.1.1.4 has been found. 
-101  Invalid character. 
The syntactic element contains an invalid character; for example, the 
command header contains an ampersand (SETUP&). This error might 
be used in place of errors -114, -121, -141 and perhaps some others. 
-102  Syntax error. 
An unrecognizable command or data type was encountered; for 
example, a string not supported by the device was received. 
-103  Invalid separator. 
The parser was expecting a separator but recieved an illegal character; 
for example, the semicolon following a program message was omitted: 
*EMC 1:CH1:VOLTS 5. 
The parser recognized a data element other than the one allowed; for 
example, numeric or string data was expected but block data was 
encountered. 
-105  GET not allowed. 
A Group Execute Trigger was contained in a program message (see 
IEEE 488.2, 7.7). 
-108  Parameter not allowed. 
More parameters were received than expected for the command 
header; for example, the *EMC common command only accepts one 
parameter, so *EMC 0, 1 is not allowed. 
-109  Missing parameter. 
Fewer parameters were contained than required in the command 
header; for example, the *EMC common command requires one 
parameter, so *EMC is not allowed.
