LEVEL DIAGRAM
To make measurements in the AF section, connect the AC level meter.
(ANT input: –53dBm, 1kHz FM, 3kHz DEV (Wide).)
In the RF section, use 470pF coupling capacitor.
(The display shows the SSG input value required to obtain 12dB SINAD without local level.)
Wide: AG is set to the MIC input becomes 3kHz DEV at 1kHz MOD.
Narrow: AG is set to the MIC input becomes 1.5kHz DEV at 1kHz MOD.
To make measurements in the AF section, connect the AC level meter.
In the RF section, use 1000pF coupling capacitor.
