2.5 1026 Syntax Interface
In addition to the default GT 9000 syntax, Model GT 9000 can also be remotely controlled
using the 1026 syntax (Giga-tronics 1026 emulation), as described below. This syntax is
selected by sending the command GT (the HP command is used to return to the GT 9000
syntax).
2.5.1 Character Representation
Command names are represented in capital letters. Small letters are used for special characters,
as shown in the table below:
Shown as Interpreted as
(cr) carriage return
(lf) line feed
s one space
z zero or more spaces
b one or more spaces
a alphabetic character
d one decimal digit
n numeric argument (see Section 2.5.2)
2.5.2 Command Format
The standard command format consists of a verb, followed by zero or more spaces, followed by
an argument. In the command GENzFIXED, GEN is the verb and FIXED is the argument. In a
few cases, the argument is omitted (the GT command, for example). Sometimes the argument
consists of a number. In the command FAz12.3E+3, FA is the verb and 12.3E+3 is the
argument.
Numeric arguments are used in the frequency and level setting commands, and are represented
in command descriptions by a lower case n. The format for numeric arguments is sufficiently
flexible that no special formatting will be needed when using most IEEE-488 controllers.
Signed or unsigned numbers are acceptable. Integers or decimal fractions are permitted and can
be followed by a signed or unsigned one or two digit exponent. Leading zeros are permitted, but
spaces within a number are not permitted. The integer and optional fractional part are each
restricted to a maximum length of 10 digits. Table 2-7 lists examples of valid numeric
arguments:
