Description
and Procedure
Use this
pro cedure
to
measure
line-related
spurs.
The
syn
thesizer
is
placed
at
a
CW
frequency
where
the
syn
thesizer
is
most
sensitiv
e
to
line-related spurs.
The
sp
ectrum
analyzer measures
the RF
output oset
by
the
harmonics
of
the
line p
o
w
er
frequency
(60
Hz
or
50
Hz).

line-related

an
In
v
ertron
is
used
to
op
erate
the sp
ectrum
analyzer
at
a
dieren
t
line
frequency
so
that
its
own
spurs
will
not
aect
the
measuremen
t.
The
sp
ectrum analyzer
must
hav
ethe
capabilit
y
of
a
10
Hz
resolution
bandwidth.
A
wider
resolution
bandwidth
results
in
the
syn
thesizer's
phase
noise
masking
the
spur.
