Command Syntax
The 1529 accepts commands that set parameters, execute functions or respond with
requested data. These commands are in the form of strings of ASCII-encoded charac-
ters. As far as possible, the 1529 conforms to IEEE-488.2, 1992 and SCPI-1994. One
notable exception is that compound commands are not allowed as explained below.
Commands consist of a command header and, if necessary, parameter data. All com-
mands must be terminated with either a carriage return (ASCII 0D hex or 13 decimal)
or new line character (ASCII 0A hex or 10 decimal).
Command headers consist of one or more mnemonics separated by colons (:). Mne-
monics may use letter characters, the underscore character (_), and possibly numeric
digits as well. Commands are not case sensitive. Mnemonics often have alternate
forms. Most mnemonics have a long form that is more readable and a short form con-
sisting of three or four characters that is more efficient.
A mnemonic may end with a numeric suffix that specifies one of a set of independent
function blocks such as input channel data paths. If a numeric suffix is omitted when a
particular block must be specified, an error is generated ("Header suffix out of range").
Query commands are commands that request data in response. Query commands have
a question mark (?) immediately following the command header. Responses to query
commands are generated immediately and placed in the output buffer. Responses
are then transmitted automatically over the RS-232 port. When using the IEEE-488
interface, responses remain in the output buffer until read or until another command is
received or the power is turned off. Responses are lost if not read before the next com-
mand is received. Each input buffer holds 128 characters and each output buffer holds
256 characters.
Some commands require parameter data to specify values for one or more parameters.
The command header is separated from the parameter data by a space (ASCII 20 hex
or 32 decimal). Multiple parameters are separated by a comma (,).
The 1529 does not allow compound commands (multiple commands per line separated
with semicolons). All commands are sequential. The execution of each command is
completed before subsequent commands are processed.
