The
HP
8753D
allows
you to
measure the
transmission and
reection characteristics
of many
ampliers
and
active
devices
.
Y
ou can
measure scalar
parameters such
as gain,
gain
atness
,
gain
compression,
reverse
isolation,
return
loss
(SWR), and
gain drift
versus time
.A
dditionally
,
you
can
measure
vector
parameters
such
as
deviation
from linear
phase,
group delay
,
complex
impedance
and
AM-to-PM
conversion.

The
analyzer
allows
you
to
make
a
swept-frequency
measurement
of
an
amplier's
second
or
third
harmonic
as
shown
in
