2Ć2

formation the oscilloscope needs to execute the command or query. ComĆ

and shown in the example in Figure 2Ć1.

Symbol
Meaning
<Header> The basic command name. If the header ends with
a question mark, the command is a query. The
header may begin with a colon (:) character; if the
command is concatenated with other commands
the beginning colon is required. The beginning
colon can never be used with command headers
beginning with a star (*).
<Mnemonic> A header subĆfunction. Some command headers
have only one mnemonic. If a command header
has multiple mnemonics, they are always sepaĆ
rated from each other by a colon (:) character.
<Argument> A quantity, quality, restriction, or limit associated
with the header. Not all commands have an arguĆ
ment, while other commands have multiple arguĆ
ments. Arguments are separated from the header
by a <Space>. Arguments are separated from
each other by a <Comma>.
<Comma> A single comma between arguments of multipleĆarĆ
gument commands. It may optionally have white
space characters before and after the comma.
<Space> A white space character between command header
and argument. It may optionally consist of multiple
white space characters.
