Selecting the Amplitude Distribution Function
Use You can select the following amplitude distribution functions for the noise
signal:
ƒ
Gaussian
Gaussian distribution functions (Gaussian factor = 5),
crest factor = 3.873
ƒ Rectangular
Rectangular distribution functions, most favourable ratio between the
RMS and peak value (crest factor = 1.732)
ƒ Triangular
Triangular distribution functions, crest factor = 2.450
Note: The setting is always valid for both channels (Ch 1&2).
Selecting the
amplitude
distribution function
1. Press the function key in the menu.
A selection field containing the available settings is displayed. The
default setting is “Rectangular“.
2. Use the rotary knob
[11] to select a setting.
3. Press the ENTER key
[5] to close the selection field.
The new setting is stored and displayed in the parameter field.
Entering the Signal Amplitude
Use You can enter the amplitude of the output signal as an RMS value. Here, the
maximum value depends on the amplitude distribution functions.
Selecting
the channel 1. Press the numeric keys 1 , 2 , or 3 to select channel Ch 1 , Ch 2 , or both
channels Ch 1&2 .
The selected channel is displayed in green in the channel display.
Entering the
signal amplitude
2. Press the function key in the menu.
An entry field containing the currently applicable setting is displayed. The
