Parameter   Description
Waveforms
Sine wave—Outputs a sinusoidal wave.
Triangular wave—Outputs a triangular wave.
Square wave—Outputs a square wave. The Set rise/fall time button becomes active when this is selected.
Signal options Frequency—The number of cycles per second of the generated signal.

Duty cycle—The ratio of on-period to off-period for a square wave.

For a triangular wave this is the percentage of time on the rising edge of the wave.

  Adjust this to create a sawtooth wave.

Amplitude—Controls the signal's voltage, measured from its DC level to its peak. If the leads are connected to the common and either the positive or the negative terminal, the wave's peak-to-peak measurement is twice its amplitude. If the output comes from the positive and negative terminals, the wave's peak-to-peak measurement is four times its amplitude.

In AC analysis, this parameter sets the AC magnitude of the injected phasor voltage. Therefore, for example, if the goal is to measure the gain using AC Sweep analysis, set the Amplitude parameter to 1.

Offset—Controls the DC level about which the alternating signal varies. An offset of 0 positions the waveform along the oscilloscope's x-axis (provided its Y POS setting is 0). A positive value shifts the DC level upward, while a negative value shifts it downward.

Set rise/fall time—Displays the Set Rise/Fall Time dialog box. This button becomes active when the square wave button is selected.
