PREamble
Example:
This example program
uses
both the
command and query
form of the
PREAMBLE
command. First the preamble
is
queried (output to the
controller). Then the preamble
is returned to the previously selected
waveform
memory.
10
DIMPre$[120]
20 OUTPUT
707;"SYSTEM:HEADER OFF"
30 OUTPUT 707;"WAVEFORM: PREAMBLE?"
40 ENTER 707 USING
"-K";Pre$
50 OUTPUT 707 USING "#,K";"WAV:PREAMBLE
";Pre$
60 END
Note
In line
50 of
the program example,
a space
is
inserted between
the
word
"PREAMBLE"
and the
closed quotation mark. This
space
must
be inside the
quotation mark
because in
this
format
(#,K) the data is
packed
together.
Failure to
add
the space
will
produce
a
word that
is
not
a
proper command word.
Example:
The
following program example brings the preamble
in
a
numeric
array.
10 DIMPreamble[1:10]
20 OUTPUT 707;"SYSTEM:HEADER OFF'
30 OUTPUT 707;°WAVEFORM:PREAMBLE?"
40
ENTER
707; Preamble)*)
50 OUTPUT 707;"WAV: PREAMBLE ";Preamble(*)
60 END
