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)
