Control Unit TX-RX Unit VCO Unit TX-RX Unit Power Module TX-RX UnitTo 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 measurements in the AF section, connect the AC level meter.
(ANT input : –53dBm, 1kHz FM, 3kHz DEV (Wide) / 1.5kHz DEV (Narrow))
The AF output level is adjusted for 0.45V/4Ω by the front panel AF VOL control.
To make measurements in 
the RF section, connect the 
RF wattmeter (50Ω). To make measurements in the AF section, connect the AC level meter.
AG is set so that MIC input becomes 3kHz/1.5kHz (Wide/Narrow) DEV at 1kHz MOD.
