6.
Analyzer
Input
Terminals
R, A,
and B
These
are
input
terminals
through which
the 4395A
receives signals
output from
the RF
OUT
terminal
and
then
fed
through the
test circuit.
How to
use these
input terminals
diers
depending on
which analyzer
mode you
use:
In
network
analyzer
mode
,use
the A
and B
terminals to
receive
signals
output
from
the
RF
OUT
terminal
and
then
fed through
the device
under test
(DUT), and
use
the
R
terminal
to
directly
feed
back
the
signal output
from the
RF OUT
terminal to
provide
the
reference
input
signal.
Y
ou
may
want to
use a
power splitter
to split
the
RF
OUT
signal
among
the
input
terminals.
In spectrum
analyzer mode
,you
can use
any
of
these
three
terminals
to
monitor
the
spectrum
of
the
input signals
.
In
impedance
analyzer mode
,which
is available
with
option
010,
use
the
R
and
A
terminals
to
monitor the
voltage and
current
across
the
DUT
being
fed
with
the
signals
output
from
the
RF
OUT terminal.
These
terminals
comply
with
INST
ALLATION
CA
TEGORY
I
of
IEC
1010-1.
Note
Do
not
exceed
the
operating
input
power
,
voltage
,
and
current
level
and
signal
type
appropriate
for
the
instrument
being
used,
refer to
your
instrument's
operation
manual.
Note
Electrostatic
discharge(ESD)
can
damage
the
highly sensitive
microcircuits in
your
instrument.
ESD
damage
is
most
likely
to
occur
as
the
test
xtures are
being
connected
or
disconnected.
Protect
them
from
ESD
damage
by
wearing
a
grounding
strap
that
provides
a
high
resistance
path
to
ground.
Alternatively
,
ground
yourself
to
discharge
any
static
charge
built-up
by
touching
the
outer
shell
of
any
grounded
instrument
chassis
before
touching
the
test
port
connectors
.
7. RF
OUT Connector
Connects the
RF output
signal from
the analyzer's
internal
source
to
a
test
set
or
power
splitter.
The output
impedance at
this connector
is
50
.
Note
that,
in
spectrum
analyzer
mode
,
the
RF
output
is disabled
by
default.
When
you
perform
zero span measurement
in spectrum analyzer mode
, you can turn the RF output on.
8. DC SOURCE (DC V
oltage/Current Output) Connector
(Option 001)
This connector, located on the front panel, supplies up to
6 40 V /
6 100 mA of DC
voltage/current.
