Syntax and Style
Program Message Formats
A program message consists of a command header, followed by its
required parameters. The parameters must be separated from the
command header by a space, for example,
*ESE 10
.
Multiple
parameters must be separated by a comma ( , ).
Each program message can contain one or more message units. The
message units in a program message must be separated by a semicolon
( ; ), for example,
*CLS;*ESE 10
.
Terminating a Program Message
The command terminator should be a linefeed <LF> plus EOI for GPIB,
and a carriage return <CR> plus a linefeed <LF> for RS-‐232. No
command processing occurs until a command terminator is received.
Command Header Variations
Each command header in the command tree has a long form and a short
form. Both forms are acceptable and each form gives an identical
response.
Examples:
:ROUTE:CLOSE 5
:ROUT:CLOS 5
:STATUS:OPERATION:ENABLE 255
:STAT:OPER:ENAB 255
The query form of a command must end with a question mark ( ? ). A
command can be entered in either uppercase characters or lowercase
characters.
