[LIN]
The

is
selected.
The

enters
the
power
(linear
value)
to
be
measured
to
the
post-detection
lter

In
other
words
,
the

calculates
logarithms
of
power
after

[LOG]
The
logarithm
type
of
VBW is
selected. The
analyzer enters
the
logarithm
value
of
power
to
be
measured
to
the
post-detection
lter
,
as
same
as
a
conventional analog
spectrum analyzer
,
which
uses
a
log-amplier
.
(The
analyzer
calculates
logarithms
of
power
before
the
post-detection
lter
.) The
logarithm VBW
makes
measurement
result 2.5
dB lower
than the
actual value
