Parameters
The
Parameters
tab, as shown in Figure 4-56, is used for setting up
the duration of the signal, the position of the marker (if required)
and the amount of memory that is allocated for this purpose. Setting
up correctly the parameters in this group is the basic and the most
important task before you start designing 3D waveforms. The
duration can be set in units of ns, us, ms, and seconds and can be
programmed within the range of 800 ns to 30,000 s.
The 3D profiler behaves just like an arbitrary waveform. The shape
of the profiler is generated using waveform points and a dedicated
3D sample clock. So, just as the basics for an arbitrary waveform
design, the duration is derived from the following relationship:
Duration = SCLK / # of waveform points
where SCLK is the 3D sample clock and the # of waveform points
can be programmed from 2 to 30,000.
Figure 4-60, Parameters Tab
The recommended method is to let the 3D composer set up the
sample clock and the numbers of points automatically for you,
however, in some cases you may want to fine tune your
requirement by pressing the Expand button. Figure 4-57 shows the
Expanded Parameters options dialog box.
Figure 4-61, Expanded Parameters Options Dialog Box
The Expanded Parameters options dialog box has three sections:
Wavelength, Modulation SCLK and Offset. The wavelength and the
modulation SCLK control the duration of the entire wave through
