2. Send programming
code "P1" (Program
data
out)
to
the
counter.
3.
Enter
the
programming
string
(43
ASCII
characters)
and
store
in
the
co
ntrollers
memory.
The
bus programming
efforts
thereafter
are
reduced
to
just
recalling
the
stored
string.
A sample program
for
HPSS
is
shown
below.
Ten
pulse

printed
out.

is
to
be st ored

Normal
programming
"Normal" means
that
the
counter
settings
are
specified
remotely,
not manually
as

vious examplel'l:

The
advantage with
"P1
•••
PS"
or
"Bus
learn"
pro-
gramming
is
that
it
requires
a knowledge
of
very
few
programming codes
(j
ust
"LP1
•••
LP8
"
or
"P1
").
Thus
preparation
and programming time
is
reduced
to
a
minimum.
The
advantage with
"nor-
mal" programming
is
that
one
ca
n
make
use
of
the
full
programming
power
and
flexibility
inherent
in
the
counter's
smart
software.

and
much
more
can be executed.
The
normal programming procedure
is:
1.
Set counter
to
default
position
(FREQ
A,
AUTO
trigger,
AC-coupling (A), Mess. time =
0.1s
etc.).
The
code used
is
"D".
2.
Program
the
changes
from
the
default
set-
tings
(e
.g.
5M2
for
2 seconds measuring
time).
A sample program
for
HPBS
is
shown
below.
Ten

"F'B")
with

Normal programming should be
made
when
the
soft-
ware must be optimized
for
its
purpose,
e.g
.
in
ATE
systems.
Note:
When
the
counter
has been switched
to
stand

it
returns
when
switched
on
again
into

after
