Step10
UP
10.Change the modulating signal frequency to 1MHz. Observe the
change in the spectrum of the FM wave and record the results in
Table 6-3.
Step11
UP
11.After the completing the experiment steps above, press the Reset
button, and minimize the amplitude of the modulating signal in
order to view the FM spectrum within a span of 50MHz. Then use
the DOWN button on the RF Synthesizer/FM module to change the
frequency of the carrier signal. See if there is any change in FM
wave spectrum. Compare this result to the original carrier
frequency of 880MHz and record it in Table 6-4.
Step12
Step13
12.Adjust the carrier frequency again. See if there is any change on
FM wave spectrum and record it to Table 6-4.
