PERFORMANCE
TESTS
NOTE
To
test
Attenuator
sections
4 through
7,
program
the
Signal
Generator
to
-12
dBm, and
key
in
[SPCL]
[8][3]
through
[8J6]
respectively,
h.
Repeat
steps
d through g with
the
UUT
programmed
to
each of the following
frequencies:
120
MHz,
244
MHz,
245
MHz,
850,
and
1050
MHz.
To
illustrate
the
procedure, Figure
4A-3
is
an example
in
which
the
measured
power and the error calculations are
shown. This example
is
for
one frequency,
and
these
measurements and
calculations are repeated
at
other frequencies. In
this case, the section errors
and
the
sum
of
the section errors are within the
test
limits
and, therefore, the unit passed.

MID-LEVEL
ACCURACY TEST
The
level
accuracy
is
verified,
from
-24
to
-66
dBm
at
frequencies of
120,
244, 245, 850,
and 1050
MHz,
using the
Power
Meter with a
Low-Level
Sensor.
REQUIREMENT
Amplitude accuracy
is
±1.0
dB
from +13
to
-I27dBm.
TEST
EQUIPMENT
Power Meter
with a
Low-Level Sensor
REMARKS
This
test,
in
conjunction with
the
High-Level Accuracy
Test
and
the
Low-Level Accuracy
Test,
verifies
the overall
level
performance of the
UUT.
It is
convenient to use the
UUT RF ON/OFF
control
when
zeroing
the
Power
Meter.
PROCEDURE
a.
Program
the
UUT
to the Instrument Preset State
[RCL]
[9][8],
and
then
program
30
MHz
and -24
dBm.
b.
Calibrate the
Power
Meter.
c.
Connect the
Power Meter
with a
Low-Level Sensor
to
the
UUT RF OUTPUT.
d.
Zero
the
Power
Meter.
e.
With
the
Power
Meter,
measure
the
UUT
output
power
(in
dBm).
It
should
agree with the
programmed
level
within
±
1.0
dB.
f.
Repeat
steps e
and
f
for levels
of -30, -36, -42, -48, -54, "60,
and
-66
dBm.
g.
Repeat
steps
d
to
g
for
frequencies of 244, 245, 850,
and 1050
MHz.
