3.16 Arbitrary Waveform
When Direct Digital Synthesis (DDS) technique is used to output the built-in waveform, the
sampling rate can reach to1200MSa/s, but it's also not a perfect way. Since DDS use interval
sample way, the higher the output frequency is, the fewer sampling points within a waveform
cycle will be. Also the details of the waveform will be lost largely and the distortion of the output
waveform will be very badly, which is not allowed in severe test. To reproduce the real electrical
signals at work site truly, now most of waveform generators use point by point way to generate
arbitrary waveform to ensure the complete details of waveform.

key to enter the editing interface. A linear waveform is preset by instrument with
waveform length 20 points, and the voltage value of each waveform point is 0.000V. The
waveform editing interface is shown as follows:
1. Voltage scale 2.X-cursor 3.Y-cursor (green line) 4. Point scale
5. Edit Parameters 6. Current waveform (yellow line and overlap 3)
