Message Terminator ____________________________________________
A message terminator indicates the end of a command.
The unit accepts the following as message terminators.
Depending on the interface setting, the following can be selected as terminators
of response messages.
Separator _____________________________________________________
(1) Message Unit Separator (Semicolon)
Semicolons are used as separators when executing compound messages. Link-
ing multiple messages by semicolons (
;
) enables a single line to be used to
describe a compound command.
If a command error occurs when messages are described in succession, the
messages from the error to the terminator are not executed.
Command processing is continued for an execution error or a query error
See
For details on errors: 8.6.4 "About Event Registers" (p. 149), and the error explana-
tions in 8.7"Message List"; (Pages 154 to 166)
(2) Message Unit Separator (Space)
A space is used as a separator to differentiate the header and data section. Add
a space ( ) between the header and data section.
(3) Message Unit Separator (Comma)
When a message has multiple data sections, a comma is used as a separator to
differentiate data sections. Add a comma (
,
) between data sections.
• LF
• CR+LF
• EOI
• LF with EOI • CR
• CR+LF
The Models 3504-40, 3504-50, 3504-60 unit analyzes a message after it has
confirmed the message terminator.
• LF with EOI (initial state)
• CR and EOI with LF • CR
• CR and LF (initial state)
Example) If
:RAN:AUTO ON;:BEEPer:KEY ON;
*
IDN?
is executed and
:RAN:AUTO
is a command error,
:BEEPer:KEY ON;
*
IDN?
following
the error will also not be executed
:RANGe:AUTO ON;:BEEPer:KEY ON; * IDN?
