INSTALLATION AND OPERATION
3. Floating Point
The floating-point numeric data format is the most flexible format. Digits may
be
the numerals 0 through 9. Any number of digits are accepted for
both
the
number
and
the exponent.
However,
numbers greater than 2,147,483,629 are
truncated, and exponents greater than
32,749
are rejected.
4.
Trigger String
The trigger string numeric data is a string of
Generator commands
terminated
with an EOR. The string may be up to 71 characters not
including the
EOR.
Commands in the string are not checked for validity until the trigger
string is
executed with the trigger command.
EOR is the end of record character. This character is selectable with
the
terminator mode command. “TMO” selects
the
linefeed character. “TMl”
selects
the
carriage return
character. The
IEEE-488 interface signal EOI
asserted with any other character
is
also considered an end of record.
EOS is
an
end
of
string character, use either or
“/’•

SUFFIX
SYNTAX
Suffixes are always one or two
alpha-characters.
Certain
suffixes
are used to scale the
numeric (the same as the front panel UNITS keys). Other suffixes mnemonically
designate
hardware
components. The five types of suffixes are described in Table
2-1

2-52. Command Descriptions
The following
paragraphs describe the remote IEEE-488 Interface operating commands
that
are not accessible from the front panel of the Generator. IEEE-488 Interface
commands
that
are accessible from the front panel of the Generator are described earlier
in this section.
