1. N-Cycle/ Gated
N-Cycle has specific number of waveform cycles, and every burst is activated by a
trigger event. Gated burst use external source to control burst when to be
activated.
2. Cycle Number
Set the number of Waveform Cycle in an N-Cycle (1 to 50,000 or Infinite).
If you choose Infinite, then a continuous waveform will be generated.

If needed, Burst Period will increase to cater to the specific number of cycles.

For an infinite-cycle Burst, External or Manual Trigger is needed to activate
burst. For Manual Trigger, a trigger will be generated for the first time when
you press Manual and stop after the second press.
3. Phase
Define the Start and the Stop Point in a waveform. The phase varies from -180°
to +180°, and the default setting is 0°. For an Arbitrary Waveform, 0° is the
phase of the first waveform point.
4. Period
Set the time span between an N-Cycle Burst to the next. If necessary the period
will increase to allow the specific number of cycles in a burst.
Burst Period> Period X Burst Number
5. Delay
Set the Time Delay between the Trigger Input and the Start of the N-Cycle Burst.
The delay should be greater than (or equal to) 0 and less than the specific burst
period.
Press View, in the Graph Mode, the waveform is shown in the following figure.
