Syntax Summary
Remote commands must contain all of the letters shown in uppercase in the command definition.
Optional letters shown in lowercase for some device dependent commands in the command
reference (Chapter 4) are useful for clarity. If any of the optional letters are included, they must all be
included, in the correct sequence.
A single white space must separate a command from its parameters or data. White space is
normally the space character. Other control characters are also interpreted as white space. Do not
use white space before the question mark in a query command.
More than one command may be in the same command string if the commands are separated with
semicolons.
GPIB uses a flexible representation for numeric parameters: integer, floating point, or
engineering/scientific notation. There are no default values for omitted parameters.
The following are examples of invalid syntax command strings that will produce errors:
