4.2 Square Wave
A square wave consists of instantaneous transitions between two voltage
levels. The
duty cycle
of a square wave represents the amount of time in
each cycle during which the wave is at the high level (assuming that the
waveform is not inverted):
DutyCycle = (Time Interval at High Level) / Period x 100%
How to generate a square wave
1.
Press the Square button to select the square wave function.
2.
Refer to Chapter 3 for configuring common parameters, including
frequency/period, amplitude and dc offset voltage.
3.
Press the softkey under DutyCycle for configuring the value.
4.
Use the knob with the cursor keys to change the value, or use the
numeric keypad to enter a desired value and then press the
softkey under % to finish the entry or the softkey under Cancel to
cancel the changes.
5.
To view all the waveform parameters, press the Graph button.
