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 a 1000pF coupling capacitor.
(The display shows the SSG input value required to
obtain 12dB SINAD Without Local Level.)
AG is set to the MIC input becomes 3kHz DEV. at
1kHz MOD. (WIDE)
To make measurements in the AF section, connect
the AC level meter.
In the RF section, use a 1000pF coupling capacitor.
