5.12.6 Burst Trigger Source
Burst trigger source: Internal (Immediate), External or Manual.
Press 〖Trig Imm/Ext〗softkey. If the Internal (immediate) source is selected, the rate at which the
burst is generated is determined by the burst period. If external source is selected, the burst count
and burst phase remain in effect but the burst period is ignored.
In the triggered burst mode, the waveform generator outputs a burst with the specified number of
cycles (burst count) each time a trigger is received by pressing〖Manual Trig〗softkey or Trig In
connector receives a TTL level signal. After the specified number of cycles have been output, the
waveform generator stops and waits for the next trigger.
In the gated burst mode, burst count is ignored but the burst period at least will be two. Press
〖Manual Trig〗softkey to enable or disable output signal. When disable output manual by manual,
input a TTL level trigger signal from Trig In connector in rear panel. If trigger signal is high level, the
output signal is enable. But if trigger signal is low level, the waveform generator will stop the level
point that corresponding to start phase until last bust is output. When the trigger signal becomes high
level, then enable the output signal again.
5.13 Dual Channel Operations
You enter the dual channel configuration menu by pressing 【Dual Channel】key.
5.13.1 Operation Mode
There are two modes for dual channel operation: parameters coupling and waveform combine. While,
parameters coupling includes frequency coupling and amplitude coupling. Using parameter coupling
way can generate two synchronous changing signal, take difference signal or multiplier signal for
example. Using the waveform combine way can add harmonic, noise or pulse on output waveforms
to realize a analog signal.
If enable the parameters coupling or waveform combine, only CHB enter into dual channel
operations. Otherwise, the two channels are still independent one.
