Description
and
Procedure
In
this
pro
cedure,
a
function
generator
is
used
to
pro
vide
a
DC
voltage
to the
synthesizer's
AM
input.
The
syn
thesizer
is set
to 0
dBm output
po
w
er.
AM
is
enabled
and
a
DC
v
oltage
is applied.
The DC
v
oltage
is
set
for
maxim
um
AM

an

v
ermo
dulation
indication
to
driv
e
the
syn
thesizer's
mo
dulator
to
the
edge
of
distortion.
The output
po
wer
is measured
with
a
p
ow
er meter.
A measuremen
t
is
made
in
1
GHz
steps
across
the
syn
thesizer's
frequency
range.
This
equipmen
t
lets

0
30
dBm.
If y

is
used
in
