Operating and Programming Guide B-7
Suffix Multipliers
Table B-2 lists the suffix multipliers that can be used with suffix
elements (except PCT and DEG).
Command Terminator
A command may be terminated with a line feed (ASCII LF character
10 decimal), a carriage return (ASCII CR character 13 decimal), or one
followed immediately by the other in any order.
Using Multiple Commands
Program Messages
Program Messages are a combination of one or more properly
formatted SCPI Commands. Program messages always go from the
DTE to the Receiver. They are sent to the Receiver over the Receiver’s
serial interface as a sequence of ASCII characters.
Program Message Syntax
Figure B-3 shows the simplified syntax of a program message. You can
see Common Commands and Subsystem Commands in the same
program message. If you send more than one command in one message,
you must separate adjacent commands with a semicolon.
