5.13.4 Waveform Combine
The Combine feature allows you to combine two outputs into one connector (CHB).
In waveform combine, select most waveforms mentioned above table except of some. Waveform
combine is similar to Sum modulation. The difference is that Sum modulation use modulating
waveform but waveform combine allows to couple CHA waveform. But continuous wave, modulating
wave, sweep wave or burst wave are all available for CHA setting. Therefore, more complicated
wave can be generated for waveform combine.
Press 〖Combine On/Off〗softkey then select On to enable waveform combine feature. The waveform
of CHA can be combined with CHB’s, then output from CHB connector.
Press 〖Combine Ampl〗softkey then configure the parameter of combine amplitude.
Combined waveform = CHA wave × combine amplitude ration + CHB wave
Press 〖Combine On/Off〗softkey then select Off to disable waveform combine feature.
5.13.5 Bursts
Make use of waveform combine feature, the waveform generator can output some special
waveforms. For example, couple two-cycle bursts with high frequency on CHB. You can operate as
following steps:
(7) Enable CHA to be continuous, 10kHz Square with duty cycle 10%.
(8) Enable CHA to be burst again, burst period 1ms and burst count 2.
(9) Press 【Dual Channel】key and set the amplitude combine to be 50%.
(10) Press 〖Combine On/Off〗softkey then select On.
(11) Enable CHB to be continuous, 1kHz Sine.
(12) Then a Sine with two-cycle bursts output from CHB connector.
5.14 Arbitrary Waveform
Press 【Utility】key then 〖Arb Edit〗softkey, then edit window and menu appears.
