8410B/C
Interface
and
Cable
The
purpose
of
J18.
The
rear
panel connector
labeled,
8410
INTERFACE,
can
be
used to provide
control signals
to
an
HP 8410B/C
network
analyzer or
an
HP
8516
S-parameter
test set (part
of
an
HP
8510
network
analyzer
system).
An
RS-232 cable
called,
SOURCE CONTROL
CABLE,
(HP
part
number
08410-60146)
provides
the
connection
between
the
instruments.
Refer
to Figure
G-18
for
an
illustration
of the
connector
and
cable.
The
interface
signals.
Several
of
the
rear
panel
functions such
as,
EXT TRIGGER
INPUT,
MUTE
OUTPUT,
PENLIFT
OUTPUT,
NEG
BLANK, and
Z-AXIS
are
provided
on
this
connector
also.
These
signals enable
multi-octave operation
of
an
HP
8410B/C.
There
is
also
a
pin
input
(LSTEPUP)
for
a
switch
closure
to
execute
the
UP
key
function,
which
increments
the
active
front panel
key.
Some
signals
on
this
connector
are
redefined
when
the
HP 8340
is
used
with
a
40
GHz
HP
8510
network
analyzer
system.

The
redefinition
occurs
when
the
HP 8510
acts
as
the
HP
8340
controller and
commands
the
synthe¬
sized
sweeper
to
provide
the
data
control lines to
an
S-parameter
test
set.
These control
lines
then
command
the
test
set to
generate
frequencies
beyond
the
normal operating
range
of
the
HP
8340.
