5.14.5 Create Arbitrary Waveform
Press〖Create New〗softkey and delete the present waveform in edit window. Draw vector lines by
above mentioned method and set the end of last vector line to be next vector line start, make the
vector lines connected end to end then an arbitrary waveform is formed. Take a triangle for example,
you can operate as following steps,
Set horizontal coordinate and vertical coordinate to be 0. Press〖Vector Start〗softkey.
(1) Set horizontal coordinate to be 2048 and vertical coordinate to be16383. Press 〖Vector End〗
softkey.
(2) Press〖Vector Start〗softkey.
(3) Press horizontal coordinate to be 4095 and vertical coordinate to be 0. Press 〖Vector End〗
softkey.
Until now, a triangle has been created. But user need to note that, the end point must be at right side
of start point, that's to say, X coordinate value of end must be greater than start. Additionally, if you
want to output a waveform with continuous period, the vertical coordinate value should be equal for
two waveform points, that one horizontal coordinate is 0 and the other is 4095.
5.14.6 Modify Arbitrary Waveform
Here introduce how to modify waveform. For example, to add a narrow pulse on a Sine, the operating
steps as below:
(1) Press【Waveform】key and select a Sine then return.
(2) Set horizontal coordinate to be 2048 and vertical coordinate be 15000. Press〖Vector Start〗
softkey.
(3) Set horizontal coordinate to be 2050 and vertical coordinate be 15000. Press〖Vector End〗
softkey.
(4) Press 〖Hor_x Zoom〗 softkey and set the pantographratio to be 18.5. Press 〖Hor_x Shift〗 softkey
and set the horizontal shift value be 2000. Then you can watch detail of added pulse.
