Half Cycle
The Half Cycle panel contains controls that select the half cycle
functions and adjust the half cycle parameters. The half cycle
functions are generated with variable and controllable delay
between the halves. If triggered mode, one half at a time is
generated as a result of a trigger signal regardless of the
programmed delay value. The half cycle functions have different
limitations compared to the standard functions; these are listed in
Appendix A. The half cycle panel and the various parameters that
control these functions are described below.

State
The State button turns on and off the half cycle waveforms function.
The half cycle function can also be selected from the Output panel.
Shape
The Shape group has controls that select the shape of the half
cycle function.
Parameters
The Parameters group has controls for programming the amplitude,
offset, start phase and duty cycle. Each channel can have an
independent set of these parameters.
The Modulation
Panels
The Modulation functions were designed over seven separate
panels, as shown in Figures 4-13 through 4-18. The panels are
invoked by pressing the Modulation header and then one of the
modulation panels that appear below it. These panels provide
access to all modulation functions and their respective parameters.
The modulation functions that are available on these panels are:
FM (frequency modulation), AM (amplitude modulation), Sweep,
ASK (amplitude shift keying), FSK (frequency shift keying) and PSK
(phase shift keying) and Amplitude and Frequency Hopping.
When modulation run modes other than continuous are selected,
there are two options that control the idle state between triggers: 1)
Carrier baseline and 2) DC baseline. When the first option is
