5. Use the Marker function to measure the carrier component of
the AM
wave
on the spectrum analyzer and the power of the
upper and lower sidebands. Use the oscilloscope to measure the
voltage at TP4 in relation to the position of the potentiometer
(i.e., the modulating amplitude). Draw the spectrum diagram in
Table 5-4.

6. Turn the potentiometer counterclockwise to the half-way
mark. Measure the voltage with the oscilloscope. By changing
the output amplitude of the modulating signal, can you observe
any change in the spectrum? Record the experiment in Table 5-4.
7. Turn the potentiometer counterclockwise to decrease the
output voltage. Measure the voltage with the oscilloscope.
Observe any changes in the spectrum of the AM wave and
record it in Table 5-4.
