GENERAL
INTRODUCTION
PM
5191
is
a
cost-effective
multifunctional
combination
of
programmable
frequency
synthesizer
and
function
generator.
The
microprocessor
contro!
enables
simple
and
rapid
operation.
The
actual
set
up
of
the
generator
is
automatically
stored
in
a
non
volatile
register,
after
power
off
and
on
again
these
para-
meters
can
then
be
used
for
a
new
instrument
setting.
PM
5191
frequency
range
covers
10
decades,
from
0,1
mHz
to
2
MHz.
And
to
make
working
with
this
.
high
precision
instrument
as
simple
as
possible
5
different
wave
forms
are
directly
selectable.
That
includes
stadard
functions
like
sine,
square
wave,
sawtooth
and
ramps.
High
precision
and
stability
are
essential
factors
in
this
instrument.
With
a
crystal
oscillator
that
serves
as
a
reference
standard
for
all
generated
frequencies,
a
high
standard
of
accuracy
is
achieved.
Together
with
outstanding
long-term
stability,
ensuring
that
today’s
signals
can
always
be
reproduced
precisely.
Frequency
resolution
is
8
digits,
so
that
full
advantage
can
be
taken
of
the
instruments
high
precision,
for
example
in
the
identification
and
measurement
of
phenomena
occuring
at
precisely
defined
frequencies.
Full
1EEE/IEC
bus
compatibility
adds
an
important
extra
dimension
to
PM
5191
versatility.
All
functions
are
remotely
selectable,
and
all
settings
and
status
data
can
be
transmitted
to
a
remote
controller
and
re-
called
whenever
required.
Completing
its
impressive
specification,
PM
5191
combines
powerful
user
features
with
operation
that
could
not
be
simpler.
The
front
panel
is
divided
into
clear,
separate
keypad
areas,
and
two
LED
displays
show
together
wirh
the
key
LEDs
frequency,
output
level,
status
and
the
modulation
function.
In
addition
to
this
manual
please
find
attached
an
operating/programming
card
for
short-form
operating
instruction
of
the
instrument.
For
adequate
customer
support
and
in
order
to
facilitate
the
service,
a
test
program
is
built
in.
Service
is
done
on
component
level,
so
no
complete
module
must
be
exchanged.

CHARACTERISTICS
Safety Characteristics
This
apparatus
has
been
designed
and
tested
in
accordance
with
safety
class
|
requirements
of
IEC-
Publication
348,
Safety
Requirements
for
Electronic
Measuring
Apparatus,
and
has
been
supplied
in
a
safe
condition.
This
manual
contains
some
information
and
warnings
which
must
be
followed
by
the
user
to
ensure
safe
operation
and
to
retain
the apparatus
in
a
safe condition.
Performance Characteristics, Specifications
Properties expressed in numerical values with stated tolerance are guaranteed by the manufacturer.
Specified non-tolerance values indicate those that could be nominally expected from the mean of a
range of identical instruments.
These
specifications
are
valid
after
a
warming-up
time
of
30
minutes
(reference
temperature
23°
C)
and
for a
termination
of the
signal
output with
50
Ohm.
If not stated otherwise, relative tolerances relate to the set value.
