To Set the Duty Cycle
Applies only to square waves. At power-on, the duty cycle for square
waves if 50%. You can adjust the duty cycle from 20% to 80% for output
frequencies up to 25 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 less than 25 MHz.
2Press 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).
