Multipath reception occurs
when in addition
to
the direct
signal
from the transmitter
an-
tenna of
a
given
station,
signals
reflected from
building walls or
mountains are also
received.
The different delays between
these two si-
gnals
can
produce
undesirable
distortions
that cannot be corrected
even by the best
re-
ceiver.
Although the
REVOX 8260-5
'
tuner offers
maximum
immunity against such
pheno-
mena, the only effective
remedy
in many
cases is to
relocate
the
antenna to
a different
position.
The true
quality
of the
received signal
can be
measured
on
the SCOPE
[36]
sockets.
A cathode
ray
oscilloscope
(with
external
X-
input) can be connected
to the SCOPE
[36]
outputs
for displaying and analyzing
the
multi-
path
reception.
The illustrations on the left
are
showing
three
kinds
of delay distortions
as displayed
on an
oscilloscope screen.
Via the sockets SCOPE
[36]
frequency deviation and signal
strength
can be displayed. lf
you
wish to make
visible
the signal strength
as
well,
an oscilloscope
with DC-input is required.
lf
you prefer
an
analog signal
meter
(needle-
type instrument) for analyzing the
strength
of
the incoming
signal,
you
can connect
it to the
SCOPE Y
[36]
output.
A 1O0pA
instrument
should be used.
