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 21 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)
3.16.2 Insert built-in waveform
If user wants to create a simple waveform, such as a Pulse or Ramp, methods ‘points edit’ and
‘linear edit’ could be used to edit out it point by point. But the two methods are inconvenient to
create the complicated waveform such as Sine, also it’s hard to make each point of waveform very
precisely.
Fortunately the build-in waveform of instrument help user to provide the available waveform
materials. Insert one of them to waveform editing area and use method of local modification or
clipping or pasting to create a complicated waveform quickly without edit it point by point.
