5. Observe the spectrum that appears. Use the Marker function
on the spectrum analyzer to determine the harmonic ratio and
draw the spectrum in Table 3-1.

After step 4 is done, make sure the "Delta" marker is used for
the next steps and not the "Normal" marker. Set the Delta
Marker to the peak point of each harmonic and make a record
by drawing a simple sketch of the spectrum in table 3-1.

6. Select the square wave on the GRF-1300A Baseband module.
Do the same spectrum measurements that were performed in
the previous steps.
Step8
7. Observe the square wave spectrum that appears on the
spectrum analyzer. Use the marker function to record the
harmonic ratio and draw the spectrum in table 3-3.
Draw the spectrum of the square wave spectrum as you did
previously for the triangle wave. Remember to remove the
delta marker ( -Marker) that was originally used with the
triangle wave.
