Two-Tone Waveform Generator
Creating, Viewing, and Modifying Two-Tone Waveforms
1. On the signal generator, press Mode Setup > Alignment Left Cent Right to Left.
2. Press
Apply Settings to regenerate the waveform.
NOTE Whenever a change is made to a setting while the two-tone generator is operating (Tw o Tone O ff
On
set to On), you must apply the change by pressing the Apply Settings softkey before the
updated waveform will be generated. When you apply a change, the baseband generator
creates a two-tone waveform using the new settings and replaces the existing waveform
in ARB memory.
3. On the spectrum analyzer, temporarily turn off waveform averaging to refresh your view more
quickly. You should now see a left-aligned two-tone waveform that is similar to the one shown in
Figure 9-5.
