Agilent Technologies HP 83711A - MULTIPLIER

MUL
TIPLIER
Invoking
the
MUL
TIPLIER
function
(pressing
the
4
SHIFT
5
key
and
then
the
4
FREQ
5
key)
allows
you
to
enter
a
multiplier
value
so
that
the
frequency
display
will
indicate
the
frequency
at
the
output
of
a
frequency
multiplier.
NO
TE
External
equipment
is
required
for
frequenc
y
multiplication.
When 4
SHIFT
5 ,
4
FREQ
5 is
pressed,
the
multiplier
value
will
be
displayed
across
the display
in
the
following
format:
FREQUENCY
MULTIPLIER
XXX
where
XXX
is
the
multiplier
value
.
The
allowable
range
for
multiplier
values
is
1
to
100.
The
preset
value
is
1
and
the
preset
up/down
arrow
increment
value
is
1.
Entering
a
frequency
multiplier
value
is
useful
when
generating
millimeter-wave
signals
with
external
multiplier
equipment.
The
display
shows
the
frequency
at
the
output
of
the
external
frequency multiplier
,not
at
the
synthesizer
RF
OUTPUT
connector
.
F
or
example
,
assume
a
frequency
of
30
GHz
is
required. The
synthesizer
cannot
generate
a
30 GHz
signal directly
,but
a frequency
doubler
can
be
connected
at the
RF OUTPUT
connector to
multiply a
15 GHz
signal by
two.
Setting
the
multiplier
value
to
two
allows
you
to
display
the
frequency
at
the
output of the multiplier on the synthesizer
. Setting the multiplier value to
two will display 30 GHz, while the synthesizer is actually generating 15 GHz.
Entering a new frequency of 32 GHz will set the synthesizer to 16 GHz.
