N-Cycle/ Gated
N-Cycle has specific number of waveform cycles, and every burst is activated by a
trigger event. Gated burst controls burst by external source.
Cycle Number
Set the number of Waveform Cycle in an N-Cycle (1 to 1,000,000 or Infinite).
If you choose Infinite, then a continuous waveform will be generate which will not stop
until a trigger event happens (Trigger button is pressed).
z
If needed, Burst Period will increase to cater to the specific number of cycles.
z
For a frequency greater than 25MHz, only a bust with infinite cycles is allowed.
z
For an infinite-cycle Burst, External or Manual Trigger is needed to activate burst.
Phase
Define the Start and the Stop Point in a waveform. The phase varies from -360° to
+360°, and the default setting is 0°. For an Arbitrary Waveform, 0° is the phase of the
first waveform point.
Period
Set the time span between an N-Cycle Burst and the next. If necessary the period will
increase to reach the specific number of cycles in a burst.
Burst Period> Period X Burst Number
Delay
Set the Time Delay between the Trigger Input and the Start of the N-Cycle Burst. The
minimum delay is a function of the specific burst period, and should always be greater
than 0.
In the Graph Mode, the waveform is shown in figure 2-60.
