Explanations
Frequency / Period
Set the signal frequency or period. The current parameter will be switched with a second press.
Amplitude / HighLevel
Set the signal amplitude or high level. The current parameter will be switched with a second press.
Offset/LowLevel
Set the signal offset or low level. The current parameter will be switched with a second press.
PulWidth/DutyCycle
Set the signal pulse width or duty cycle. The current parameter will be switched with a second press.
Rise/Fall
Setting the rise edge or fall edge for pulse waveform. The current parameter will be switched with a
second press.
Delay
Setting the delay for pulse waveform.
Menu Explanations of Pulse Waveform
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 specifications.
The default value is 200 μs. 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 generator will change the waveform immediately.
