Program
Example H2:
When
the 3455A is in the Binary mode, another feature
called the
“Learn
Mode" can be used.
With
this feature, the set-up of the instrument (F1T3, etc) can
be
learned
by the
controller
to be used later on in the program. This can be accomplished
by
sending the
34S5A
an ASCII “B“
in
the Data
Mode
and
reading the next four bytes output by the instrument into a str-
ing
variable.
The instrument can then be reprogrammed
to
the previous
set-up by using the string
variable
instead of program codes. It is important to remember to program the 34SSA into the
Binary
mode
by
sending an ASCII “B“.
The instrument can transfer Us set-up information to the controller
in the Binary
mode only. The
following
programs
show how
the “Learn Mode" feature can
be
used.
These programs are written in the HP Basic, HPL, and
Enhanced Basic languages.
