press CLEAR . Otherwise, press the menu button next to the baud
rate you require. Then press CLEAR to remove the menu from the

Command Formats
Commands, front panel setups, and waveforms sent over the RSĆ232
interface are composed of ASCII character strings. The ASCII characĆ
ters represent hexadecimal numbers, with two characters per number.
(See Front Panel Encoding for the meanings of the numbers.)
The general RSĆ232 command format is
cmd arg:data;
where
cmd is the command;
arg is an argument to the command; and
data is any additional data needed for the command.
There must be a single white space (either a space or a tab) between
the command and argument. There must be no white space on either
side of the colon delimiter between the argument and the data. The
semicolon is the command terminator, but a carriage return also
terminates the command. Semicolons are necessary only in multipleĆ
command strings.
NOTE
The interface executes a command as soon as it receives
the command terminator. If you place multiple commands
on one line, the interface executes them in sequence. You
can abort a command bysending an escape character.
Commands, Queries, and Responses
Figure AĆ11 shows the set of commands and queries sent to the
instrument and the responses sent by the instrument. Explanation for
each is given in the following text.
