Sum Modulation (Sum)
In Sum Modulation (Sum), the modulating signal is added to the carrier
waveform. A typical use is adding gaussian noise to a carrier signal. The
waveform generator will accept an internal or external modulation
source.
For more information on the fundamentals of a sweep, refer to chapter 5,
“Tutorial.”
To Select Sum Modulation
• The waveform generator allows a modulating signal to be added to
the carrier as a percentage of the carrier waveform amplitude in
resolution of 0.01%.
• The waveform generator will allow Sum modulation to be added to
any carrier waveform.
• Front-Panel Operation : You must enable Sum before setting up any
of the other modulation parameters. Press , then select
Square
.
Press and then press
Type
and
Sum
. At this point, you can
specify the other modulation parameters. Once you have done so,
press
Modulate
to turn on modulation.
• Remote Interface Operation : To avoid multiple waveform changes,
enable Sum after you have set up the other modulation parameters.
