TEST LEVEL CALIBRATION
Rev050321
With the calibration test setup configured as shown in
Figure 18, set the
frequency of the signal generator and measuring instrument to 150 kHz
(without modulation).
WITHOUT exceeding
[the 1 dB gain compression point of the power
amplifier
minus 5.1 dB
]
, adjust the amplitude setting of the signal
generator until the amplitude measured on the measuring instrument is
equal to the
U
mr-ATT(xx)
value (
1.5 dB)
calculated as described in section
6.2.1 for the open circuit test level (
U
o
) for which calibration is being
performed.
Record
either:
the
frequency
(f
x
)
and amplitude setting of the signal generator
(SGout)
-or-
the frequency
(
f
x
)
and measured forward power
(FWDpwr)
See examples of calibration data/results tables below.
Increase the frequency of the signal generator and measuring
instrument by a maximum of 1% of the present frequency, as described
in section 6.2.3.
Repeat steps 2 through 4 until the next frequency in the sequence
would exceed the highest frequency of the calibration/test. For tests
up to 80 MHz, there should be at least 633 test frequencies; and for tests
up to 230 MHz, there should be at least 739 test frequencies.
