Creating, Viewing, and Optimizing Multitone Waveforms
6. Press Edit Item > -10 > dB.
7. Highlight the value (0) in the Phase column for the tone in row 4.
8. Press
Edit Item > 123 > deg.
9. Press
Apply Multitone.
NOTE Whenever a change is made to a setting while the multitone generator is operating (Multitone
Off On
set to On), you must apply the change by pressing the Apply Multitone softkey before
the updated waveform will be generated. When you apply a change, the baseband generator
creates a multitone waveform using the new settings and replaces the existing waveform in
ARB memory.
You have now changed the number of tones to 10, disabled tone 2, and changed the power and phase of tone
4. Figure 8-4 on page 174 shows what the multitone setup table display on the signal generator should look
like after all steps have been completed. The spectrum analyzer should display a waveform similar to the
one shown in Figure 8-5 on page 175. Notice that even-numbered multitone waveforms have a small amount
of carrier feedthrough at the center carrier frequency.
