Amplifier Saturation Check
1) With the calibration test setup configured as shown in
Figure 11
or
Figure 12
, set the frequency of the signal generator to 150 kHz (without
modulation).
2)
Adjust the signal generator output to either:
a) the respective SGout value determined during calibration for the
present test frequency;
-or-
b) the level at which the power indicated by the power meter is
equal to the respective FWDpwr value determined during
calibration for the present test frequency.
3) Record the amplitude measured on the spectrum analyzer as
(U
mr
)
.
4) Increase the signal generator output by 5.1 dB, and record the
amplitude measured on the spectrum analyzer as
(U
mr(inc)
)
. The
difference between
(U
mr
)
and
U
mr(inc)
)
must be between 3.1 dB and 7.1
dB.
5) Increase the frequency of the signal generator to the next test
frequency.
6) Repeat steps (2) through (5) until the next frequency in the sequence
would exceed the highest frequency of the test.
