HP 8753D - Measurements Using the Tuned Receiver Mode

Measurements Using
the Tuned
Receiver Mode
In
the
tuned
receiver
mode,
the analyzer's
receiver operates
independently of
any signal
source
.
This
mode
is
not
phase-locked and
functions in
all sweep
types.
The analyzer
tunes
the
receiver
to
a
synthesized
CW
input signal
at a
precisely specied
frequency.
All phase
lock
routines
are
bypassed,
increasing
sweep
speed signicantly
.The
external source
must
be
synthesized,
and
must
drive the
analyzer's external
frequency reference
. The
analyzer's
internal
source
frequency
is
not
accurate
,and
the internal
source should
not
be
used
in
the
tuned
receiver
mode
.
Using
the
analyzer's
tuned
receiver
mode
is useful
for automated
test applications
where
an
external
synthesized
source
is
available
and
applications where
speed is
important. Although
the
tuned
receiver mode
can function
in all
sweep types
,
it
is
typically
used
in
CW
applications
.
