To make measurements in the RF section, connect the RF level meter.
In the RF section, use a 0.01µF coupling capacitor.
(The display shows the SSG input value required to obtain 12dB SINAD.)
To make measurement in the AF section, connect the AC level meter.
(ANT input: –53dBm, 1kHz FM, 1.5kHz Dev (Narrow).)
The AF output level is adjusted for a 0.6Vrms/8ohm by the Volume knob.
To make measurements in the AF section, connect the AC level meter.
AG is set so that MIC input becomes 1.5kHz (Narrow) DEV at 1kHz MOD.
To make measurements in the RF section, connect the RF Wattmeter (50ohm).
