To Set the Duty Cycle of a Square Wave
At power-on, the duty cycle for square waves is 50%. You can adjust the
duty cycle from 20% to 80% for output frequencies up to 5 MHz. The
following steps show you how to change the duty cycle to 30%.
1 Select the square wave function.
Press the key and then set the desired output frequency to any
value up to 5 MHz.
2 Press the
“
Duty Cycle
”
softkey.
The displayed duty cycle is either the power-on value or the percentage
previously selected. The duty cycle represents the amount of time per
cycle that the square wave is at a high level (note the icon on the right
side of the display).
3 Enter the desired duty cycle.
Using the numeric keypad or the knob, select a duty cycle value of “30”.
The function generator adjusts the duty cycle immediately and outputs a
square wave with the specified value (if the output is enabled).
