AFT Center turn
Frequency
/ fAFTC
PIF Freq. :
38.9MHz
Others : Preset
(1) Input a signal that f0=38.9[MHz], 60[dB( V)] at pin 79.
(2) As read the bit of “AFT center”, sweep up the input signal
frequency.
(3) Measure the lowest frequency that the bit of “AFT center” is
“0”, shown as below. That is fAFTC
AFT center 1
fAFTcxxx
frequency
f0
[Read BUS DATA] The bit of "AFT center"
AFT center 0

/ fAFTW(n)L
/ fAFTW(n)H
/f AFTW(w)L
/ fAFTW(w)H
PIF Freq. :
38.9MHz
Others : Preset
(1) Input a signal that f0=38.9[MHz], 60[dB( V)] at pin 41.
(2) Set the bit of “AFT window” to “(0), narrow”.
(3) As read the bit of “AFT window”, sweep up the input signal
frequency.
(4) Measure the highest frequency but lower than f0 (38.9MHz)
that the bit of “AFT window” is “0”, shown as below. That is
fAFTw(n)L.
(5) Measure the lowest frequency but higher than f0 (38.9MHz)
that the bit of “AFT window” is “0”, shown as below. That is
fAFTw(n)H.
(6) Set the bit of “AFT window” to “(1), wide”.
(7) Measure as (3) ~ (5), that is fAFTw(w)L, fAFTw(w)H.
AFT window 1

S-trap reduction
(1) Input a signal composed of following 3 signals at pin 79;
38.90[MHz]/90[dB(mV)],
33.40[MHz]/80[dB(mV)]
(2) Set the "Strap" of IICBUS to "0(h) off"
(3) measure the output level of 5.5MHz component for pin #68
by spectrum analyzer. -> V68 (strap off)
(4) Set the "Strap" of IICBUS to "4(h)"
(5) measure the output level of 5.5MHz component for pin #68
by spectrum analyzer -> V68 (strap on)
(6) Calc the result of reduction
Strap = V68 (strap off) - V68 (strap on)
