Figure 3-45, Programming Phase Offset between Channels
Contrary to what was discussed in the above, there are two
waveforms that behave differently; these are sine and triangular
waveforms. You can still use the phase offset method as was
described in the above however, the two functions are different in a
way that you can change the start phase on each waveform in
increments of 0.2° regardless of how many waveform points are
being used for generating the shape. This is true even if the number
of waveform points do not allow such resolution however, it is also
limited to 50MHz maximum. The phase offset for sine and triangle
are changed from the Standard Sine and Standard Triangle menus
and not from the Outputs menu. When you change start phase on
one channel, you automatically generate a phase offset between
the two channels, provided that both channels generate the same
waveform shape. The phase adjustment for the sine and triangle
waveforms is accessed from the Waveform->Standard->Phase
menu, as shown in figure 3-46.
