Pulse Generator
The Pulse Generator panel contains controls that select the pulse
function and adjusts the pulse parameters. The pulses are
generated digitally suing the arbitrary waveform memory and digital
computation and therefore, there are some limitations to the
minimum to maximum range that must be observed. The pulse
design limitations are given in Appendix A. The various parameters
that control the digital pulse generator features are described
below.

Pulse Mode
The Pulse Mode group has controls to turn on pulse generator
functions, select of the output generates single or double pulse
shape and selects the pulse polarity from one of the Normal,
Complemented and Inverted options.
Polarity
The Polarity group has controls to select between Normal,
Complemented and Inverted pulse shapes.
Pulse Parameters
In the pulse parameters group you adjust the complete set of
parameters that builds up the pulse shape. Included are: period,
rise and fall times, high time delay and high and low amplitude
levels.
To display and modify parameters, click on the and next to the
required parameter change and modify time per your requirements.
The range of each parameter is specified in Appendix A.
