Reection
Response
in
Time
Domain
The
time
domain
response
of
a
reection
measurement
is
often
compared with
the time
domain
reectometry
(TDR)
measurements
.
Like
the
TDR,
the analyzer
measures the
size of
the
reections
versus
time
(or
distance).
Unlike
the
TDR, the
time domain
capability of
the
analyzer
allows
you
to
choose
the
frequency
range
over which
you would
like to
make the
measurement.
