Level Setting Process
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) 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 spectrum analyzer is
equal to the
(U
mr-30dB
)
value (±1.5 dB) calculated for the open circuit
test level
(U
o
)
for which calibration is being performed (see section
4.4.2.1).
3)
Record either:
(a) the frequency (fx) and amplitude setting of the signal generator
(SGout)
-or-
(b) the frequency (fx) and forward power measured using the power
meter/sensor (FWDpwr).
See examples of calibration data
tables on the right.
4) Increase the frequency by a maximum of 1% of the present frequency
(see section 4.4.2.3).
5) Repeat steps (2) through (4) until the next frequency in the sequence
would exceed the highest frequency of the 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.
