Product Tours Help
These Product Tours are just a structured sequence of web pages. Click the ► button to step through them.
- The navigation buttons have the following functions:
- |◄ takes you back to the beginning of the current tour
- ◄ is the same as your browser back button
- ▲ takes you up a level in the hierarchy
- ► steps forward to the next page
- The drop-lists give another way of accessing the same pages
- shows and hides a map of the structure of the tour with links to each page.
- expands the tour into its own window (only visible when embedded in another page.)

TGxA Series Function Generators: Noise generation
noise can be used as a waveform, a modulator,
or summed with the output
White Noise
All models can generate gaussian
white noise to a
-3dB bandwidth of 20MHz.
The noise generation algorithm
achieves a high crest factor (peak to rms ratio) of
5.27.
Amplitude is adjustable between 10mV
pk-pk and 10V pk-pk into 50 Ohms.
Adding Noise to a waveform
Noise can be added to any waveform except pulse.
The amount of noise added can be specified as 0% to 50%
of the amplitude of the carrier waveform.
Modulating with Noise
Noise can be used as the modulating waveform for AM, FM,
PM or PWM modulations using any of the carrier waveforms
allowable for that modulation type.
