Conditions
Same condition VOUT1. Measure T9B signal.
Same condition VOUT2. Measure T9B signal.
Input signal: CAR=4.5MHz, DEV=±25kHz, MOD=5kHz, Level:
100mVp-p. T5A input. T6=4.2V, M1=T9B signal level.
DEEM=20log(M1/VOUT1)
Input signal: CAR=6.5MHz, DEV=±25kHz, MOD=5kHz, Level:
100mVp-p. T5A input. T6=0.6V, M1=T9B signal level.
DEEM=20log(M2/VOUT2)
T11=4.5V, T6=4.2V, T5A=4.5MHz, 100mVp-p. T12A=A1.
T5A=6.5MHz. 100mVp-p. T12A=B1. TRP1=20log(B1/A1)
T11=4.5V, T6=0.6V, T5A=4.5MHz, 100mVp-p. T12A=A1.
T5A=6.5MHz. 100mVp-p. T12A=B1. TRP2=20log(A1/B1)
T6=4.2V. T5A=4.5MHz, 300mVp-p. Measure T12 signal level.
T6=0.6V. T5A=6.5MHz, 300mVp-p. Measure T12 signal level.
T6=4.2V. T5A=4.5MHz, 30mVp-p. Measure T12 signal level.
T6=0.6V. T5A=6.5MHz, 30mVp-p. Measure T12 signal level.
T6=4.2V. T11=4.5V, T5A=4.5MHZ, 100mVp-p.
Measure T12 signal level.
T6=0.6V. T11=4.5V, T5A=6.5MHz, 100mVp-p.
Measure T12 signal level.
Input signal: CAR=4.5MHz, DEV=±25kHz, MOD=1kHz,
T6=4.2V. When T9B signal is OK, then measure T5A FM input
level range.
Input signal: CAR=6.5MHz, DEV=±25kHz, MOD=1kHz,
T6=0.6V. When T9B signal is OK, then measure T5A FM input
level range.
