SG input level for 12dB SINAD are obtained measured by
AF VTVM
connecting SG to each point via a 0.01µF capacitor.
AF level obtained when the AF output level is adjusted for 0.45V/4Ω with
the front panel AF VOL control. Measured with AF voltmeter connected
to the external speaker jack, receiving a –53dBm SSG signal modulated
at 1kHz, DEV. 3kHz (Wide), 2.4kHz (Semi-wide), 1.5kHz (Narrow).
