Transmitter Section AF(1kHz) RF(435.05MHz) IC16 Q9 Q10 Q11 Q12 ANT FILTER MIC MIC AMP vco ANT 50 9.70Vrms 0.83Vrms -20.00dBm 7.33dBm 5.67dBm 14.17dBm 11.50dBm 26.33dBm 14.00dBm 27.50dBm All voltage levels must be measured at High power transmission. The RF and IF sections are measured by using a spectrum analyzer. After setting the standard (1 kHz, 3 kHz Dev.) deviation, each voltage of the AF section is measured by using an AF VTVM or osciloscope. The level for each point is measured without removing parts or cutting the pattern.
