Program Header Options; Program Data - HP 54501A Programming Reference Manual

Program
Header
Options
Program
headers can be
sent
using
any
combination
of
uppercase or
lowercase
ASCII
characters.
Instrument
responses,
however, are always
returned
in uppercase.
Both program command
and query
headers may be
sent in either
longform (complete spelling), shortform (abbreviated spelling), or
any
combination
of longform
and shortform.
Either of
the following examples
turn the headers
on.
:SY?TEM:HEADERON
-longform
:SYCT:HEAD ON
-
shortform
Programs written in longform are easily read and are almost
self-documenting.
The
shortform
syntax conserves
the amount of
controller
memory
needed for program storage and reduces the amount
of
I/O
activity.
Note
The
rules
for shortform
syntax are
shown in the
chapter
"Programming
and Documentation Conventions."
Program Data
Program data
is
used to convey
a
variety of
types
of parameter
information related to the command header.
At
least one space must
separate the command header
or query
header from
the program data.
< program mnemonic > < separator >
<data>
< terminator >
When
a
program mnemonic or query
has
multiple data parameters
a
comma
separates sequential
program data.
< program mnemonic > <
separator
> <
data
>,
<
data
>
< terminator
>
For
example,
:TRIGGER:DELAY
TIME,1.23E-01 has two data
parameters:
TIME
and 1.23E-01.
