(7) Tune signal generator No. 1 down until the first minimum is found.
TI
indication will be between -2 dB and 0 dB.
(8) Tune signal generator No. 1 down until TI indicates -6.00 dB.
(9) Record signal generator No. 1 frequency as Freq. #1.
(10) Decrease signal generator No. 1 frequency by 1.6 kHz.
(11) TI display will be ≤-30 dB.
(12) Decrease signal generator No. 1 frequency by 3 kHz.
(13) TI display will be ≤-80dB.
(14) Tune signal generator No. 1 up until TI indicates 0 dB, and then continue on
until TI indicates -6.00 dB.
(15) Record signal generator No. 1 frequency as Freq. #2.
(16) Subtract Freq. #1 from Freq. #2. The difference should be between 12.4 and 16.9 kHz.
(17) Increase signal generator No. 1 frequency 18.5 kHz above frequency recorded as
Freq. #1.
(18) TI display will be ≤-30 dB.
(19) Increase signal generator No. 1 frequency by 3 kHz.
(20) TI display will be ≤-80 dB.
(21) Connect equipment as shown in figure 19 below.
(23) Set signal generator No. 2 for a frequency output of 800.455 MHz at a level of 0 dB.
