MAINTENANCE
PERFORMANCE TESTS
This
test verifies
the high-level
accuracy of
the
Generator and
also
verifies
that the
amplitude correction factors for the individual Attenuator
sections are correct. This
test,
in
conjunction with the mid-level accuracy
and
low-level accuracy
tests,
verifies
the
overall level
performance of
the
UUT.
PROCEDURE
a.
Calibrate
and
zero the
Power
Meter.
b.
Program
the
UUT
to
[RCL]
[9][8].
c.
Connect
the
Power
Sensor
to the
UUT RF
OUTPUT.
d.
Program
the
UUT
frequency to 0.4
MHz.
e.
Select
each attenuator
section
by
programming
the
UUT
amplitude
to the levels
shown
in
Figure
4A-2 High-Level Accuracy
test
conditions,
and
record the
measured
power
at
each
level.
f.
For each
programmed
level
of Figure 4A-2,
compute
the output
power
error
(subtract the
programmed power
in
dBm
from
the
measured power
in
dBm).
These
errors
must
not exceed
±
1.0
dB.
g.
For
attenuator
sections
1
through
7,
subtract the
measured power
for section
zero
from
the
sum
of the
measured power
for that section
and
the
nominal
attenuation for that
section,
e.g.,
(-M0+M1+6)
for section
1.
The
eight section
errors
and
their
sum
must
not exceed
±
1.0
dB.
Figure
4A-2 shows
the
parameters of the high-level accuracy
test.
