5.15 Arbitrary Waveform
There are two types for arbitrary waveform setting, short and long arbitrary waveform,
the methods of which are same. Waveform length for short is 16384 (16k) points and
allows being set independently for dual channels. Waveform length for long is 1048576
(1M) points and only applicable for channel A.
5.15.1 Enter into the Waveform Edit
Press 【Waveform】key to display all the waveform option and select 〖Arbitrary〗key to
enter into the arbitrary waveform menu. If you want to create the waveform with length
less 16K points, you can press〖Create Normal〗key. If you want to create the waveform
with length more than 16K points, you can press〖Create Ultra Long 〗key. Once enter
into the window of waveform edit, generator pre-create one straight line with length of 20
points, voltage of each points is 0Vdc and sampling rate is 1MSa/s. The interface is as
below:

5.15.2 Insert Built-in Waveform
To create a simple waveform, like a Pulse or Ramp, you can edit by “Point Edit” and
“Line Edit” methods manually. But for Sine, it is not so easy to edit manually because the
each point requires extremely accurate value. So the generator prepares 150 built-in
arbitrary waveform for users, the part of each waveform can be selected and inserted to
current edited waveform. Then user can correct, cut and copy it to complete the desired
complicated waveform, no need to edit point by point.
During the editing, user can change the parameters such as sampling rate, amplitude
and waveform length to alter the characteristic of editing waveform timely.
