(2) If Gated is selected, only external source was available for trigger, the detail
description refer to chapter 5.14.
5.13.3 Burst Period
Press 〖Burst Period〗softkey to set the burst period. The burst period defines time from
the start of one burst to the start of the next burst. The burst period must be long enough
to accommodate the setting counts, see below formula,
Burst Period > Burst Count/Frequency of Burst Signal
If the burst period is too short, the waveform generator will automatically adjust it to be
allowed minimum value. Once the frequency of burst signal changes and leads to the
burst period can’t hold the burst count, the generator will automatically adjust it to be
allowed minimum value.
5.13.4 Burst Count
To set the burst count, press〖N Cycles〗 softkey The burst count defines the number of
cycles to be output per burst. The burst count must be short enough to be held in burst
period. See below formula to clarify the relationship between burst count and burst
period.
Burst Count < Burst Period×frequency of burst signal
If the burst count is too long, the waveform generator will automatically increase the burst
period up to its maximum value to accommodate the specified burst count
5.13.5 Burst Phase
The start phase defines the start time and stop time always at the same phase of
waveform for burst signal. To set the burst phase, press the 〖Burst Phase〗softkey.
5.13.6 Trigger Source
Press〖Trig Imm/Ext〗softkey. When Immediate selected, the waveform generator takes
internal source and output burst signal continuously. The setting of burst period is valid.
When manual mode selected, the waveform generator outputs one burst signal each
time you press 〖Manual Trig〗 softkey. When External selected, generator takes
external source and the setting of burst period is invalid, the detail description refers to
chapter 5.14.
