period.
The pulse width and pulse duty cycle are correlative. Once a parameter is changed, the other will
be automatically changed. The pulse duty cycle is limited by the "Minimum Pulse Width" and
"Pulse Period".

Press [Wave] > Pulsesoftkey to select the pulse wave function and press Width softkey to
highlight it.At this point, use the numeric keypad to input the value and select the desired unit from
the unit menu that pops up, or use the direction keys and knob to modify the current value.
1. For the input method of the value, refer to the introduction in
"Parameter Setting
Method".
4. The width units available are sec, msec, μsec and nsec.
3.Press [Utility] > unitsoftkey and press Width/Dutysoftkey to change Width in the parameter to
Duty.Press [Setting] >Dutysoftkey to modify the duty cycle parameters.
Leading/Trailing Edge Time
The leading (rising) edge time is defined as the time required for the pulse amplitude to rise from
10% threshold to 90% threshold; while the trailing (falling) edge time is defined as the time
required for the pulse amplitude to fall from 90% threshold to 10% threshold as shown in the
figure above.
The range of the leading/trailing edge time is limited by the pulse width currently specified as
shown in the formula below. The edge time will be automatically adjusted to match the specified
pulse width if the value currently set exceeds the limit value.
Leading/Trailing Edge Time ≤ 0.625 × Pulse Width
Press [Wave] > Pulsesoftkey to select pulse wave function and press Edge Time softkey to enter
the Edge Time sub-menu.Press Leading or Trailing softkey to highlight it.At this point, use the
numeric keypad to input the value and select the desired unit from the unit menu that pops up, or
use the direction keys and knob to modify the current value.
1. For the input method of the value, refer to the introduction in
"Parameter Setting
Method".
2. The edge time units available are sec, msec, μsec and nsec.
3. The leading time and trailing time are independent from each other and users can set them
separately.
2.2.9 Enable the Channel Output
After configuring the parameters of the waveform selected, waveform output could be enabled.
Press[Output1] or/and [Output2] button on the front panel and the backlight of the button turns
on. The instrument outputs the configured waveform from the [Output1] or [Output2] connector
on the front panel.
