2. RSSI (H) Sensitivity Adjustment

 • Perform the adjustment at T1CH (26CH : 43.780MHz)  as a rule.
Setting :

Procedure :
 

1

 FM rf signal generator condition :

Carrier frequency

: 43.780MHz

Modulation frequency

: 20Hz (EXT)

 Use the oscilloscope to confirm the FM rf signal generator in-

put (AF) signal waveform and RSSI signal, and use the RV101
so that they are synchronized matched (duty is synchronized).
