Multitone and Two–Tone Waveforms (Option 430)Using Multitone ModulationFigure 12-5For details on each key, use key help as described on page 42.The Random Seedsoftkey that affects theMultitone’s phase valuesis not used in the followingexamples and is shownfor reference, only.5. Press Done.You now have a multitone setup with five tones spaced 20 kHz apart. The center tone is placed atthe carrier frequency, while the other four tones are spaced in 20 kHz increments from the centertone.Configuring Tone Powers and Tone Phases1. Highlight the value (0 dB) in the Power column for the tone in row 2.2. Press Edit Table > Edit Item > –4.5 > dB.3. Highlight the value (0) in the Phase column for the tone in row 2.4. Press Edit Item > 123 > deg.Removing a Tone1. Highlight the value (On) in the State column for the tone in row 4.2. Press Toggle State.Generating the WaveformPress Return > Multitone Off On until On is highlighted.This generates the multitone waveform with the parameters defined in the previous sections. Duringwaveform generation, the M-TONE and I/Q annunciators activate and the multitone waveform isstored in volatile ARB memory. The waveform is now modulating the RF carrier.Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide 303
