There are a few ways to approach pulse generation with a waveform generator. For one, your instrument may have a dedicated front panel button. In the case of Teledyne LeCroy's WaveStation 2000 waveform generators, entering the instrument's Pulse menu will enable you to manipulate all of the defining parameters of a pulsed waveform (Figure 1). These include: frequency, period, amplitude, high/low level, offset, pulse width, duty cycle, and delay. That gives you a rather broad latitude of variability.

cycle of a square wave.

The bottom line is that a well-equipped waveform generator gives you a number of options for creating pulsed waveforms with a wide range of characteristics. If your application calls for frequencies higher than 50 MHz or so, you may need to turn to a dedicated pulse generator. But for less stringent applications, waveform generators offer everything you'll need in pulsed waveforms.
