Remote command:
[:SOURce<hw>]:LFOutput<ch>:SHAPe:TRAPeze:PERiod
Trapezoid Rise – LF Generator
(This feature is available for shape mode Trapezoid only)
Sets the trapeze shape rise time.
Remote command:
[:SOURce<hw>]:LFOutput<ch>:SHAPe:TRAPeze:RISE
Trapezoid Fall – LF Generator
(This feature is available for shape mode Trapezoid only)
Sets the fall time for the trapeze shape of the LF generator.
Remote command:
[:SOURce<hw>]:LFOutput<ch>:SHAPe:TRAPeze:FALL
Trapezoid High – LF Generator
(This feature is available for shape mode Trapezoid only)
Sets the high time for the trapeze shape of the LF generator.
Remote command:
[:SOURce<hw>]:LFOutput<ch>:SHAPe:TRAPeze:HIGH

Noise Settings
The parameters for the level distribution and the bandwidth for the noise source are
provided in the "Noise Generator" section of the dialog. The settings affect all analog
modulations which use the noise generator as the internal modulation source.
Distribution - Noise
Selects the noise power density distribution of the noise.
"Gaussian"
The noise power density has a Gaussian distribution.
"Equal"
The noise power density has an even distribution.
Remote command:
[:SOURce<hw>]:NOISe:DISTribution
Bandwidth - Noise
Enters the noise bandwidth. Distinct bandwidth settings between 100 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. The noise level in
the frequency band is indicated at Noise level (System Bandwidth).
Remote command:
[:SOURce<hw>]:NOISe:BANDwidth|BWIDth
Noise Density - Noise
Indicates the level of the noise signal for a bandwith of 1 Hz.
