To Set the Rise/Fall Edge
Rise edge time is defined as the duration of the pulse amplitude rising from 10 % to 90 % threshold, while fall edge time is defined
as duration of the pulse amplitude moving down from 90 % to 10 % threshold.
The setting of rise/fall edge time is limited by the currently specified pulse width limit. Users can set rise edge and fall edge
independently.
1.
Press
[Waveforms] → [Pulse] → [Rise]
to set the rise edge.
The rise edge shown on the screen when the instrument is powered on is the default value or the set value of the last power down.
If you want to set the waveform by fall edge, press the Rise/Fall key again, to switch into the fall edge parameter (the current
operation is displayed in inverse color).
2.
Input the desired rise edge.
Use the numeric keyboard to input the parameter value directly, and press the corresponding key to select the parameter unit. Or
use the arrow keys to select the digit to edit, and then use the knob to change its value. The generator will change the waveform
immediately.

Note:
The methods of setting other parameters of the pulse signal are similar to the sine waveform function.
5.5. TO SET NOISE WAVEFORM
Press
[Waveforms]
key to select the waveform function, and press the
[Noise]
softkey. The noise parameters are set by using
the noise operation menu.
The parameters for noise include
stdev
, mean and bandwidth. As shown in Figure 32, in the soft key menu, select Stdev. The
stdev parameter area is highlighted in the parameter display window, and users can set the stdev value here. Noise is non-periodic
signal which has no frequency or period.
