(9) Position synthesizer/level generator controls for a 50 MHz, -86 dBm output and
connect equipment as shown in figure 2, CONNECTION A.
Figure 2. +15 and +25 dBm accuracy equipment setup.
(10) Adjust synthesizer/level generator output level to within RF power amplifier
input operating range. Slowly increase RF power amplifier gain control for a power meter
indication of -5 dBm.
(11) Use precision power measurement technique used in paragraph 8 a (7) through
(12) above; calculate power and record as P2.
