Figure 3-34, Double Pulse Mode
Double Delay
The Double Delay parameter programs the delay between the two
adjacent pulses. This parameter is active only when the double
pulse mode is turned on.
Sync Position
The Sync Position parameter programs the position of the sync
output along the pulse cycle. The position is the only parameter that
is programmed in units of waveform points. The location of the sync
is visible on the screen below the pulse icon and the number of
points that are used for building the pulse shape is shown below the
horizontal axis.
Channel State
The channel state comes in handy when programming pulse
parameters for one channel only. This option is specifically useful
because you may want to program one channel while the other
channel was already programmed before and its parameters may
collide with the new parameters that you are programming on
another channel. When you select the Channel State OFF option,
you may freely program all parameters on the other channel and
the OFF channel will not be computed but will generate a dc level at
its output terminal.
Keeping in mind that the pulse is created digitally, using memory
points, one should understand there are limitations of creating such
pulses that evolve from this system. These limitations are
summarized below.
