Multitone and Two-Tone Waveforms (Option 430)
Using Multitone Modulation
Figure 17-5
5. Press Done .
You now have a multitone setup with five tones spaced 20 kHz apart. The center tone is placed at
the carrier frequency, while the other four tones are spaced in 20 kHz increments from the center
tone.
Configuring Tone Powers and Tone Phases
1. 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 Tone
1. Highlight the value (
On
) in the
State
column for the tone in row 4.
2. Press Toggle State .
Generating the Waveform
Press Return > Multitone Off On until On is highlighted.
This generates the multitone waveform with the parameters defined in the previous sections.
During waveform generation, the
M-TONE
and
I/Q
annunciators activate and the multitone
waveform is stored in volatile ARB memory. The waveform is now modulating the RF carrier.
Configuring the RF Output
1. Set the RF output frequency to 100 MHz.
The Random Seed
softkey that affects the
Multitone’s phase values
is
not used in the following
examples and is shown
for reference, only.
