Setup
With
the
RF
power-sensor
output
connected
to
the
power
meter
,
connect
the
input
of
the
RF
power
sensor
to
the
RF
OUTPUT
of
the
tracking
generator
.
Description
This
test
measures
the
incremental
RF
output
amplitude
accuracy
of
the
tracking
generator
over
021
dBm
to
010
dBm,
the
range
of
the
automatic
level
control
(ALC).
The
tracking
generator
frequency
is
set
to
300
MHz,
the
ALC
normal
detector
is
selected,
and
the
tracking
generator's
attenuator
(if
present)
is
set
to
0
dB.
The
tracking
generator
output
power
is
set
to
010
dBm ,
and
a
reference
reading
is
taken
with
the
power
meter
.
The
output
power
is
then
stepped
in
1
dB
increments
over
the
021
dBm
to
011
dBm
range
.
The
absolute
error
between
the
programmed
amplitude
(what
was
expected)
and
the
power
meter
reading
(what
was
measured)
is
stored.
The
dierences
in
the
absolute
errors
are
checked
to
see
if
they
meet
incremental
specications
.
The
above
procedure
is
repeated
at
1
MHz
with
the
ALC
alternate
detector
.
In
Case
of
F
ailure
If
this
test
fails
,
the
following
modules
may
need
repair
or
adjustment:
