9.3 Noise Setting
The noise generation function can provide Gaussian noise with a settable bandwidth.

Set the waveform parameters
The waveform parameters of noise include "Stdev" and "Mean". Since the noise obeys a
Gaussian distribution (normal distribution), mean (m) and standard deviation （ σ ） can
characterize its distribution characteristics. The setting method refers to a sine wave.

Set the bandwidth
To set the bandwidth of noise, first click the switch area in the bandwidth switch setting box to
open the bandwidth setting, then click the value area in the bandwidth setting box, at last type
the value and unit in the pop-up virtual keyboard.
Application example: set CH2 to output noise of the following parameters
Stdev= 100 mVrms
