G. Messages
-100 Command error
Error has occurred in which the E4991A could not grammatically specify the error
message. It shows that the command error which is defined by the IEEE488.2,5.1.1.4 has
occurred
-101 Invalid character
In the series of error message characters, invalid character has been found. For example,
when a message "SENS:CORR1:COLL:FPO USER" is sent toward the proper program
message; "SENS:CORR1:COLL:FPO&USER", the ampersand symbol (&) will be
perceived by E4991A as an invalid character. In case the parameter is inputted at the end,
provide space between the command and the parameter.
-102 Syntax error
There was an unrecognized command or data type. For example, when a message
"SYST:POFF" is sent toward the proper program message; "SYST::POFF", a column (:)
has been incorrectly inserted and it will be perceived by E4991A as unrecognized
command. Delete one column (:) in order to send the appropriate command.
-103 Invalid separator
When the parser (compiler) was expecting a separating symbol, there was a character
which is not a separating symbol. For example, when a message
"SENS:CORR1:COLL:FPO USER;*OPC?" is sent toward the proper 2 program
messages with a semi-column (;) separating the two; "SENS:CORR1:COLL:FPO USER
*OPC?", the separating semi-column (;) will be perceived by E4991A as a space. When
sending 2 program messages simultaneously, please insert a separating symbol between the
two, such as semi-column (;).
-104 Data type error
The parser has recognized data element that should not supposed to exist. For example,
even though a numerical figure or series of character data have been expected, a block data
have been sent. Define the type of the recognized data.
-105 GET not allowed
During the receiving of program message, Group Execution Trigger (GET command in
HTBasic) have been inputted (refer to IEEE4888.2,7.7). For example, send a command
such as "*OPC?", or "*WAI" which weigh the programs.
-108 Parameter not allowed
Parameter exceeded the number necessary for a command.
For example, when a message "SWE:TYPE LIN,SEGM" is sent toward the proper
program message;
"SWE:TYPE LIN", even though the parameter required for this command is 1, 2
parameters are contained. Therefore, the number of the parameter will be regarded as
invalid by E4991A. Refer to the command reference and check the number of parameters
required.
-109 Missing parameter
Parameter was less than what was necessary for a command, or the parameter has not been
inputted. For example, SWE:POIN command requires 1 parameter and thus, when a
message; "SWE:POIN" has been sent toward the correct program message; "SWE:POIN
201", it will be regarded as invalid by E4991A because the parameter has not been
inputted. For command which requires parameter, make sure they are inputted.
