The settings for the noise source are offered in the "Noise" section of the "LF Output" menu of the "Mod Gen" block. This setting affects all analog modulations which use the noise generator as the internal modulation source
Source Internal, Noise only
Selects the noise power density distribution of noise.
"Gaussian" | The noise power density has a Gaussian distribution. |
"Equal" | The noise power density has an even distribution. |
Source Internal, Noise only
Enabled /disables bandwidth limitation of noise.
"On" | The noise signal is generated within the set frequency bandwidth. The noise level in the frequency band is indicated at "Noise Level (System Bandwidth)" ("LF Output" menu of the "Mod Gen" block). |
"Off" | The noise signal is generated within the maximum bandwidth of 10 MHz. The noise level per Hz is indicated at "Noise Level - Noise" ("LF Output" menu of the "Mod Gen" block) |
Indicates the level of the noise signal per Hz in the total bandwidth.
Remote command:Source Internal, Noise only
Enters the noise bandwidth in case bandwidth limitation is enabled. Distinct bandwidth settings between 10 kHz and 10 MHz in 100 kHz steps (range 100 .. 1 MHz), 1 MHz (range 1 MHz .. 5 MHz) and 5 MHz (5 MHz … 10 MHz) are possible.
The noise signal is generated within the set frequency bandwidth. Noise level per Hz and noise level in the system bandwidth are indicated at "Noise Level (System Bandwidth)" ("LF Output" menu of the "Mod Gen" block).
Remote command:Indicates the noise level in the system bandwidth for enabled bandwidth limitation. Distinct bandwidth settings between 10 kHz and 10 MHz in 100 kHz steps are possible.
