2. Select "Pulse Mode = Double".
3. Set "Pulse Period = 10 us".
4. Set "Pulse Width = 2 us".
5. Set "Double Pulse Width = 1.2 us".
6. Set "Double Pulse Delay = 4.5 us".
7. Activate "Pulse Output State".
8. Set "Trigger Mode = Auto".
In the "Pulse Graph" tab, you can view the generated pulse signal graphically.
To enable pulse modulation
1. Select the "Pulse Modulation" tab.
2. Set "State = I" to activate pulse modulation.
3. Set "RF > On" to enable signal output.
