The Model
2500
is
specially
designed
for
cellular

and
includes
a
"Go-No-Go"
automatic

enables
the
user
to
program

parameters
for
trouble

purposes.
A
non-volatile

allows
the
user
to

In
the

the
Model
2500
generates

steps.
The
RF
output
leyel
is
continuously
variable
from
0.1
uVolts
to
10
mVolts
in
five
ranges.
The
Model
2500
contains
a 1 kHz
modulation
source,
a
10
Hz
to
10
kHz
audio
synthesizer
and
an
external
modulation
input.
The
audio
synthesizer
output
has
a
second
independently
variable
output
on
the
front-panel.
Deviation
markers
at
±5
kHz
or
±600

may
be
superimposed
on
the
demodulated
output
for
viewing
on
an
external
oscilloscope
in
both
the
Receive

modes.
The
Model
2500
measures

carrier
frequency,

Power
may
be
applied
to
the
RF
in/out
connector
for
measuring
R.F.
power
up
to
110
watts
(when
terminated
into
a
true
50

load).
Twenty
memory
registers
are
available
for
storing
and
recalling
all
front-panel
keyboard
settings.
An
optional
RS-232
interface
and
two
available
software
packages
allow
for
its

PROGRAM
PARAMETERS
When
the
Model-2500
is
used
in
t~e
cellular
test
mode
for
the
first
time,
it
may
be
necessary
to
define
certain
cellular
system
parameters
prior
to
testing
a
cellular
telephone.
This
is
accomplished
by
selecting
the
PROGRAM
PARAMETERS
selection
from
the
CELLULAR
TEST
MENU,
followed
by
the
"ENTER"
key,
and
then
programming
the
parameters
that
follow.
These
parameters
are
saved
in
a
non-volatile
memory
when
power
is
removed
from
the
Model-2500.
The
factory
default
·
values
for
these
parameters
in
the
non-volatile
memory
are
set
to
typical
values
that
may
be
used
for
testing
cellular
telephones.
However,
in
special
cases,
you
may
want
to
redefine
these
parameters
to
suit
the
needs
of
your
test
procedure.
The
programmable

that
may
be
