Test
Sequencing
T
est
sequencing
is
an analyzer
function that
allows you
to automate
repetitive tasks
.Y
ou can
create
a
sequence
as
you
are
making a
measurement. Then
when you
want to
make that
same
measurement
again,
you
can
recall
the
sequence and
the analyzer
will repeat
the previous
keystrokes
.
The
following
is
a
list of
some of
the key
test sequencing
features
available
on
the
HP
8753D
network
analyzer:
Limited
decision-making
functions
increase
the
versatility
of the
test sequences
you create
by
allowing
you
to
jump
from
one
sequence to
another.

GOSUB
SEQUENCE
function
that
allows
you to
call other
sequences as
sub-routines.
Y
ou can
create,
title,
save
,
and
execute
up
to
six
sequences
.
Y
ou can
save
your
sequences
to
a
disk
using
the
internal
disk
drive
.
Y
ou
can
use
the
parallel
port
as
a
general
purpose
input/output
(GPIO)
bus
to
read
ve
TTL
input
bits
in a
decision
making
function,
and
send
eight
TTL
output
bits
to
control
a
peripheral.

The
analyzer
completes
all
operations
related
to
the
following commands
before continuing
with
another
sequence
command:
single sweep
number of groups
auto scale
marker search
marker function
data ! memory
recall or save (internal or external)
copy list values and operating parameters
CHAN1, CHAN2, Wait 0*
