Distribution
Selects the distribution of the noise power density.
"Gauss"
Generates the noise power according to a Gaussian distribution.
"Equal"
Generates an evenly distributed noise.
Remote command:
[:SOURce<hw>]:NOISe:DISTribution on page 1181
Bandwidth
Sets the noise bandwidth as distinct value.
You can set the bandwidth between 100 kHz and 10 MHz in 100 KHz steps.
The noise signal is generated within the set frequency bandwidth. The noise level in
the frequency band is defined by "Noise Level (System Bandwidth)".
Remote command:
[:SOURce<hw>]:NOISe:BANDwidth|BWIDth on page 1180
[:SOURce<hw>]:NOISe:BWIDth:STATe on page 1181
