Chapter 4, GPIB Commands
The Syntax of Program Messages
The Syntax of Query Messages and Response Messages
Commands other than those described in the command reference as “No Query”
can be used as Query commands. To send a Query command as a message, add a
?
to the end of the character string as shown in the example below.
*IDN?
Commas and semicolons are used to separate data in response messages. Commas
are used to separate multiple return values in response to a Query command.
Semicolons are used to separate the responses to multiple Query commands
transmitted as one message. As an example, the response to the message
:QUERY1?;QUERY2?
is shown below.
<data1>,<data1>;<data2>,<data2>
<newline><^END>
is transmitted at the end of the message to indicate the end of
the message.
