2. Connect channel 1 (X) of the oscilloscope to the NBFM AUDIO OUTPUT of the FM / PM Receiver.Slowly vary the frequency using the frequency control of the RF Generator. How does the 1.5kHz signal vary with the frequency of the RF signal.
주파수가 10.690MHz ~ 10.721MHz 범위를 벗어나면 신호가 차단되어 나타나지 않는다. 이 범위가 RF Generator의 upper and lower frequency limits이다.
