Setup
Procedure
Note
All
non-specied
spectrum-analyzer
settings
are
left
in
the
A
UTO
mode
.
1.
Set
the
spectrum-analyzer
center
frequency
to
10
MHz,
frequency
span
to
50
kHz,
and
reference
level
to
+10
dBm.
2.
Set
the
synthesized-source
frequency
to
10.0
MHz
and
adjust
the
amplitude
for
a
0
dBm
power
reading
on
the
power
meter
.
Connect
the
RF
OUTPUT
of
the
synthesized
source
to
the
DUT's
EXT
REF
input.
3.
Set
the
spectrum-analyzer
marker
to
the
highest
peak
and
note
the
amplitude
of
the
carrier
frequency
.
It
should
be
approximately
0
dBm.
4.
Note
the
harmonics
amplitude
as
you
change
the
spectrum-analyzer
center
frequency
setting
to
20
MHz,
30
MHz,
40
MHz,
50
MHz,
60
MHz,
70
MHz,
80
MHz,
and
90
MHz.
At
each
frequency
,
the
harmonics
amplitude
should
be
20
dB
below
the
carrier
.
