Spurious Responses
Description
Internal
reections
within
the
instrument
can
cause
spurious
signals
to
be
displayed
along
with
the
true
signals
.
The
level
of
the
spurious
signals
depends
on
the
magnitude
of
the
reections
from
the
device
being
tested.

,
if
a

signal
was
measured using
the 1550

would
be
