8.3.2 Command SyntaxThe 1529 accepts commands that set parameters, executefunctions or respond
with requested data. These commands are in theform of strings of ASCII-en-
coded characters. As faras possible, the 1529 conforms to IEEE-488.2, 1992
and SCPI-1994. One notableexception is that compound commands are not al-
lowedas explained below.
Commands consist of a command header and, if necessary,parameter data. All
commands must beterminated with either a carriage return (ASCII 0D hex or
13 decimal) or newline character (ASCII 0A hex or 10 decimal).
Command headers consistof one or more mnemonics separated by colons (:).
Mnemonics may use lettercharacters, the underscore character (_), and possi-
bly numericdigits as well. Commands are not case sensitive. Mnemonics often
havealternate forms. Most mnemonics have a long form that is more readable
and a short form consistingof three or four characters thatis more efficient.
