To Set the Pulse Width/DutyCycle
Pulse width is defined as the time from the 50% threshold of a rising edge
amplitude to the 50% threshold of the next falling edge amplitude (as shown in
the figure below). The pulse width setting range is limited by the ―Minimum
Pulse Width‖ and ―Pulse Period‖ setting. For detailed information, please refer
to ―SDG2000X Datasheet‖. The default value is 200μs.
Pulse duty cycle is defined as the percentage that the pulse width takes up in
the whole period. Pulse duty cycle and pulse width are correlative. Once a
parameter is changed, the other will be automatically changed.
1. Press Waveforms→ Pulse → PulWidth, to set the pulse width.
The pulse width shown on the screen when the instrument is powered on is
the default value or the set value of last power down. If you want to set the
waveform by duty, press the PulWidth/DutyCycle key again, to switch into the
duty parameter (the current operation is displayed in inverse color).
2. Input the desired Pulse Width.
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
