5.13. To Output Pulse Signals
Press
button to call the user interface of Pulse signal, the Pulse waveform
parameters can be set by operating the Pulse setting menu on the right.
The parameters of Pulse waveform are: Frequency/Period, Amplitude/High Level,
Offset/Low Level, Pulse Width/Duty. You can operate the menu by using the menu
selection buttons on the right.
To set the Frequency/Period, Amplitude/High Level, Offset/Low Level, please refer to "To
Output Sine Signals
”.

Term Explanation
Pulse Width:
There are two kinds of Pulse Width
—positive and negative.
Positive Pulse Width is the time span between thresholds of 50% of the rising edge
amplitude to the next 50% of the falling edge amplitude.
Negative Pulse Width is the time span between thresholds of 50% of the falling edge
amplitude to the next 50% of the rising edge amplitude.
Pulse Width is determined by Period and Duty Cycle;
the formula is: Pulse Width = Period * Duty Cycle.
