Multitone Waveform Generator

Creating, Viewing, and Optimizing Multitone Waveforms

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 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 190. Notice that even- numbered multitone waveforms have a small amount of carrier feedthrough at the center carrier frequency.
