Using the Instrument
Using the Half Cycle Waveforms
Figure 3-39, the Digital Pattern Menus
There are various settings that define how the instrument will
Half Cycle Menus
generate half cycles. For example, spacing between the halves can
be programmed to any length between 200 ns to 20 s. The half
cycle menus are described below.
Half Cycle Shape – defines the shape of the half cycle waveform.
There are three types of waveforms that can be halved: sine
triangle and square.
Delay – defines the delay between the halves. The delay can be
programmed from 200 ns to 20 s with increments of 20 ns.
Frequency – defines the frequency of the half cycle waveforms as
if they were combined to a single cycle waveform. Actually, if you
want to calculate the period of the half cycle use the following
relationship:
Half Cycle Period = 2 / frequency
Amplitude – defines the amplitude level of the half cycle waveform.
The same level is used throughout the instrument when you move
from waveform shape to another.
Offset – defines the offset level of the half cycle waveform. The
same level is used throughout the instrument when you move from
waveform shape to another.
Phase – defines the start phase of the half cycle waveform. The
first cycle starts with this phase offset setting and the second half
starts 180° later.
