To Set the Pulse Width

1. Press Pulse  Width, to set the Pulse Width.

The Pulse Width shown on the screen is the default value when the instrument is

powered or the set value beforehand. When changing the function, if the current

value is valid for the new waveform, it will be used sequentially.

2. Input the desired Pulse Width.

Use the keypad or the knob to input the desired value, choose the unit, and press

the corresponding button. The Generator will change the waveform immediately.

Setting the Pulse Width

Key Points:

 Pulse width is limited by the minimum pulse width and the Pulse

period.

Minimum Pulse width= 20ns

Pulse width ≥ Minimum Pulse width

Pulse width ≤ Pulse period－Minimum Pulse width

 Pulse duty cycle is limited by the minimum pulse width and the Pulse

period.

Pulse duty cycle ≥ 100 × Minimum Pulse width ÷ Pulse period

Pulse duty cycle ≤ 100 × (1－Minimum Pulse width ÷ Pulse period)

 Settings of “Pulse Width” and “Duty Cycle” are equivalent.

Once a parameter is changed, the other one will change accordingly. For instance,

the current period is 1ms, the pulse width is 500µs and the duty cycle is 50％,

when setting the pulse width to be 200µs, the duty cycle will become 20％.

 About the setting method of “Duty Cycle”, please refer to the

introduction about the “Duty Cycle” of the Square.
