TK-8302/8302H

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, 3kHz Dev (WIDE) / 1.5kHz (NARROW))

The AF output level is adjusted for a 0.47V/4ohm by the front panel AF VOL control.

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.

To make measurements in the RF section, connect the RF Wattmeter (50ohm).
